There are situations that seem small from the outside, but feel completely different on the inside.
A delayed reply.
A short message.
A different tone.
And suddenly, it doesn’t feel neutral anymore. It feels personal.
What is rejection sensitivity?
There is a term that is often used in connection with ADHD: rejection sensitive dysphoria (RSD).
It describes a very intense emotional reaction to perceived rejection, criticism, or disapproval. Not only obvious rejection, but also situations that could be interpreted that way.
Important to say: this is not an official diagnosis. You won’t find it in diagnostic manuals. But it is widely discussed in ADHD-related research and articles, for example on platforms like Additude or Healthline.
It’s not about what happens. It’s about what it feels like.
What makes this difficult is not just the situation itself.
It’s how certain the conclusion feels.
If someone doesn’t reply, my brain doesn’t think “they’re probably busy”.
It goes straight to: something is wrong.
How it shows up in real life
I can be out with a group of people, have a completely normal evening, and still spend the next three days thinking about it.
Did I talk too much?
Was I annoying?
Did I say something weird?
And I don’t just think it once. I replay the entire situation and try to find the exact moment where I might have crossed a line.
If I make plans with friends at 8pm and they don’t reply to my message by 7, my brain doesn’t assume they are busy.
It assumes something changed.
Maybe they don’t want to see me anymore.
Maybe there’s something serious we need to talk about.
Maybe they just don’t like me.
In relationships, it can get even more intense.
If my partner is stressed and a bit quieter, the logical explanation would be that he had a long day.
But that’s not where my thoughts go.
Instead, it becomes: he is distant, something is off, maybe he is losing interest, maybe he wants to end things.
I’ve had situations where I was completely convinced of something that wasn’t real.
One example I remember very clearly: my boyfriend went out partying before we were officially together. The next day, he didn’t reply to me until the late afternoon.
Even though we had been close the day before, I was 100% sure that there was another girl at his place.
Not as a thought. As a certainty.
The problem is not the thought — it’s the intensity
Everyone has insecure thoughts sometimes.
The difference is how intense they feel and how quickly they take over.
It’s not a passing thought. It becomes a full narrative.
And once that narrative is there, it’s hard to step out of it.
The cycle
It often follows the same pattern:
Something small happens.
My brain interprets it negatively.
The emotion hits immediately and strongly.
Then the overthinking starts.
I replay conversations, analyze details, imagine scenarios, and try to “figure out” what went wrong.
And the more I think about it, the more real it feels.
Why this is linked to ADHD
Rejection sensitivity is often discussed in connection with ADHD because of emotional dysregulation.
ADHD is not only about attention. It also affects how emotions are processed and regulated.
Reactions can be faster, stronger, and harder to control.
So a situation that might feel mildly uncomfortable for someone else can feel overwhelming or deeply personal.
It’s not just “being too sensitive”
For a long time, I thought this was just part of my personality.
That I was overreacting, overthinking, or just “too much”.
But the more I understand it, the more I see that it’s not about being weak or dramatic.
It’s about how strongly things are experienced internally.
Final thought
The hardest part about rejection sensitivity is not that these thoughts exist.
It’s that they feel completely real in the moment.
Even when nothing actually happened.
And learning to separate what I feel from what is actually happening is something I’m still working on.
