A short reply to a long message. A look from your manager. A friend who hasn’t texted back. For a lot of people with ADHD, small moments like these can hit hard and fast. Here’s what “rejection sensitive dysphoria” means, what the research does and doesn’t support, and a simple private log you can bring to your next appointment.

Not medical advice. This article is general education. It isn’t a diagnosis, a treatment plan or a substitute for therapy or professional guidance. If rejection or criticism is affecting your mood, relationships or safety, please talk to your GP, psychologist or psychiatrist. If you’re in Australia and need to talk to someone now, Lifeline is on 13 11 14.

You send a message to the group chat and nobody replies for an hour. By the time someone does, you’ve already rewritten the story: they’re annoyed with you, you said the wrong thing, you always say the wrong thing. Your chest is tight. Part of you knows it’s out of proportion. The rest of you doesn’t care.

People in ADHD communities often call this rejection sensitive dysphoria, or RSD. The phrase spread because it names something a lot of people feel and couldn’t put into words. It also gets used as if it were an official diagnosis, and it isn’t. Both of those things can be true at the same time, and it helps to keep them apart.

What people mean by RSD

The term was coined and popularised by US psychiatrist Dr William Dodson. He describes RSD as an intense emotional reaction to the perception (not necessarily the reality) of being rejected, teased or criticised, or of falling short of your own standards or other people’s. He writes that it can be turned inwards and look like a sudden drop in mood, or turned outwards and look like a flash of anger. Some people work very hard to please everyone. Others stop trying things at all, because trying feels too risky.

That description comes from his clinical experience. In 2024 Dodson and colleagues published a case series of four of his patients and noted that, until then, the concept hadn’t been examined in the scientific literature. A case series is a starting point for research. It doesn’t show how common something is or what causes it.

Is RSD a diagnosis?

No. Rejection sensitive dysphoria isn’t a diagnosis in the DSM-5-TR (the American Psychiatric Association’s manual) or in the WHO’s ICD-11. You won’t find formal criteria for it, and there’s no validated test for it. If someone online tells you that you “have RSD”, that’s a description they’re using, not a clinical finding.

What is in the DSM-5-TR is a little closer than you might expect. In its section on associated features of ADHD, it says emotional dysregulation or emotional impulsivity commonly occurs in children and adults with ADHD, and that people with ADHD describe themselves, and are described by others, as quick to anger, easily frustrated and emotionally overactive. Those are associated features, not diagnostic criteria. That’s the better-studied ground RSD sits on.

What the research does support: emotional dysregulation

Emotional dysregulation is a broad term for emotions that come on fast, run hot and take a long time to settle. It has a much bigger evidence base than RSD.

• It’s common. In a 2014 review in the American Journal of Psychiatry, Shaw and colleagues estimated that emotion dysregulation shows up in around 25–45% of children and 30–70% of adults with ADHD. Those adult figures come mostly from clinic samples. The same review is clear that many people with ADHD don’t have impairing emotional symptoms.
• It’s more than a mood day. A 2020 meta-analysis by Beheshti, Chavanon and Christiansen pooled 13 studies of 2,535 adults. Adults with ADHD reported much higher emotional dysregulation than people without ADHD, and emotional lability (moods that swing quickly) showed the biggest gap. The more severe the ADHD symptoms, the more emotional dysregulation people tended to report.
• There’s no agreed definition yet. A 2019 practitioner review led by Stephen Faraone found emotional symptoms are common and persistent in ADHD and cause real impairment. Some researchers argue they should count as core symptoms. The authors also noted there’s no consensus on how to define these symptoms in a way that is specific to ADHD.

The Shaw review also pointed out that current ADHD treatments often ease emotional dysregulation as well as attention symptoms. If you’re on ADHD medication or thinking about it, questions about the emotional side belong with your prescriber. This article isn’t the place for medication advice.

What about rejection sensitivity itself?

“Rejection sensitivity” is an established idea in psychology: a tendency to anxiously or angrily expect rejection, notice it quickly and react strongly. A handful of studies have looked at it in ADHD, and the picture is mixed.

• In a survey of 1,235 German 10- to 19-year-olds, Bondü and Esser (2015) found that young people with more ADHD symptoms reported higher anxious and angry rejection sensitivity. Rejection sensitivity partly explained the link between ADHD symptoms and other problems such as low mood and conduct difficulties.
• Babinski and colleagues (2019) studied 391 young adolescents during a computer game in which peers “accepted” or “rejected” them. Kids with more ADHD symptoms showed a bigger early brain response to rejection, reported more rejection sensitivity, and responded less to being accepted.
• Not every study agrees. In a small 2007 study of 78 university men, Canu and Carlson didn’t find higher rejection sensitivity in those with ADHD, although the ADHD groups did report lower self-esteem. A much larger 2026 survey of more than 4,000 US college students found ADHD symptoms and rejection sensitivity were positively related.

So what’s fair to say? Rejection sensitivity seems to be higher on average in people with more ADHD symptoms, especially in younger samples. The research is still small, mostly based on questionnaires, and it doesn’t tell you anything about any one person. What it does do is give you, and your clinician, a sturdier set of words than a label from social media.

Why it can feel so big

Plenty of things can look like rejection sensitivity from the outside: anxiety, depression, trauma, a rough patch at work, not enough sleep. Sorting out which is which is a job for a clinician, not a blog post. From the inside, though, a few ADHD-shaped patterns come up again and again:

• The reaction arrives before the pause. If the pause before acting is harder for you (one of the executive functions that ADHD research focuses on), the hurt and the reply can land before you’ve had a chance to check the facts.
• A history of being corrected. Lots of people with ADHD grew up hearing “you’re not trying” and “you forgot again”. That history can make the next bit of criticism feel like proof of an old story.
• Time blindness makes waiting worse. Ten minutes without a reply can feel like forever when time is hard to sense.
• It mixes with overwhelm. On a day with too many open loops, a small knock can tip everything over. That’s the territory of ADHD overwhelm.

From my side of it

I was diagnosed with ADHD in 2024, about six months after my daughter. I’ve spent two decades working in tech, and for most of that time I didn’t have a name for some of what went on in my head. Time blindness, hyperfocus at the wrong moment, obsessions that burn bright and fade, and emotions that run hot, including a strong reaction to feeling rejected or criticised. None of that went away with a diagnosis. It did become easier to notice, and easier to talk about with the people who help me.

RSD is something I deal with every day. I work hard to please people, at work and at home, and I often feel I never quite give enough attention to either. So when I’m already self-conscious about something and someone makes a comment, it lands hard.

Here’s a work example. I’ll go above and beyond to deliver something that was considered impossible, and then I’m asked to change or tweak it. It’s hard not to take that as a personal shot. I have to work to remind myself that they probably don’t know how hard it was to build, or how hard it would be to change for what is a small difference in the outcome. They aren’t saying I haven’t done enough.

My default is defensive mode, and for me that often means defence by offence. In a corporate job, that doesn’t help you in the long run.

The medication I’ve been on for nearly two years helps. It gives my brain a bit more time to process before my mouth starts. I take a breath, and I’ll often say, “Let me take that one away and get back to you.” My biggest win was realising I don’t have to give a definitive answer on the spot. (That’s my experience, not advice. Medication questions belong with your prescriber.)

Part of the reason I built iFocusFlow was for my family. A place to put things down so they stop rattling around was one of the first things I wanted. That includes feelings, not just tasks.

Why write it down at all?

In the moment, a strong reaction feels like the whole truth. A day later it often looks different, but by then the details have gone. Writing a few lines straight after a hard moment gives you something concrete to look back on, on your own or with a therapist.

There’s some lab evidence that naming a feeling can take a little heat out of it. In a 2007 brain imaging study, Lieberman and colleagues found that putting a label on an emotional image (affect labelling) dampened activity in the amygdala, a brain region involved in emotional responses. That was a lab study in adults without ADHD looking at pictures, so it isn’t proof that journalling treats anything. It’s a reasonable reason to try writing a word or two down.

The bigger benefit is practical. Most of us walk into an appointment and can’t remember what happened a fortnight ago. A log gives your psychologist real examples to work with instead of a vague “it’s been a bad few weeks”.

A simple log you can keep

Keep it short. You’re more likely to stick with five lines than a page. After a moment that stung, write down:

1. What happened. Just the facts, as a camera would see them. “Sent a long message. Got ‘ok’ back.”
2. What I told myself. The story your brain wrote. “She’s sick of me.”
3. Body and mood. Where you felt it and how strong it was, on a 1–10 scale. “Tight chest, hot face, 8.”
4. What I did. No judgement, just a record. “Deleted my reply, went quiet for the night.”
5. What I’d say to a friend. If a mate showed you the same message, what would you tell them? “She’s at work. ‘Ok’ is just ‘ok’.”

If you can, add one line the next day: how it looks now. That follow-up is often the most useful part.

Spotting patterns over a few weeks

One entry won’t tell you much. A few weeks of them might. Every week or two, read back over your notes and look for:

• Repeat triggers. Is it mostly feedback at work? Waiting for replies? One particular relationship?
• Conditions. Were the big ones on short-sleep days, busy days or hungry evenings?
• The gap. How often did the story you told yourself match what actually happened?
• What helped. Stepping away, a walk, waiting before replying, talking to someone.

Bring what you notice to your clinician. They can help you work out what it means and what to try. Patterns in a log are a conversation starter, not a self-diagnosis.

Where iFocusFlow fits, and where it doesn’t

iFocusFlow is an ADHD planner, not an emotional-regulation tool and not therapy. It can be a handy place to keep a log like the one above, especially if pen and paper tend to go missing.

• A private journal in Brain Dump. Brain Dump doubles as a private journal, with mindfulness and mood check-ins. You can jot down the five lines above in a minute, straight after it happens.
• Locked with Face ID. You can secure the journal with Face ID, so a quick note about a hard moment stays yours.
• No account. You don’t need to sign up to use it. The app doesn’t collect usage or personal data. The details are in the privacy policy.
• It’s on the devices you carry. iFocusFlow runs on iPhone, iPad, Mac and Apple Watch, so the log is close by when you need it.

Some people like to scroll back through their entries with their therapist, others prefer to read out a summary. Either way, you choose what to share. If you’d like the planning side too, the ADHD planner page covers the rest of the app.

Privacy matters more for this kind of note

A note about feeling rejected is about as personal as notes get. Before you write that kind of thing into any app, it’s worth checking its privacy disclosures on the App Store. We’re not making claims about other apps. For iFocusFlow, core use doesn’t need an account, the app doesn’t know who you are or what you write, and we don’t collect app-usage or personal data. The only events we receive are de-identified App Store purchase events if you buy Pro. Your journal stays on your device, with optional iCloud sync if you want it on your other devices.

When to get more help

Talk to your GP, psychologist or psychiatrist if reactions to rejection or criticism are hurting your relationships or your work, if you’re avoiding things you care about, or if your mood drops and stays low. If you ever feel unsafe or have thoughts of harming yourself, contact emergency services on 000, or Lifeline on 13 11 14, straight away. Outside Australia, use your local emergency number or crisis line.

A log is a support for that help, not a replacement for it.
