Why Does Rejection Feel So Painful?

I don't know whether you've ever had this happen.

You send someone a message and they don't reply.

An hour goes by and you're absolutely fine.

A couple more hours pass and suddenly your brain starts filling in all the blanks.

Have I upset them?

Were they offended by what I said?

Have I completely misread our friendship?

Then, just as you've convinced yourself the relationship is hanging by a thread, your phone lights up.

Sorry, only just seen this! It's been manic today!

That's it.

Nothing was wrong at all.

Most of us have probably done something similar at some point, but for some people those thoughts don't just pop into their minds every now and then. They seem to arrive at lightning speed and they're incredibly difficult to shake off. It's exhausting because, even when part of you knows you're probably overthinking it, another part of you is already bracing itself for rejection.

I think that's one of the hardest things to explain to somebody who doesn't experience it. It's not about being dramatic or wanting reassurance every five minutes. In fact, many people are desperately trying not to let anyone know what's going on in their head. On the outside they might look completely calm while, internally, they're replaying conversations from three days ago and wondering whether a full stop at the end of a text message means someone's annoyed with them.

Our brains are fascinating really.

They're constantly trying to work out whether we're safe. Thousands of years ago, belonging to a group wasn't just nice to have, it was essential for survival. Being excluded could have had serious consequences. Although our lives look very different now, our brains still care enormously about whether we're accepted by the people around us.

For some people, though, that emotional alarm system seems to become incredibly sensitive. It's a bit like having a car alarm that goes off every time a leaf lands on the bonnet. It's trying to do its job, but it's reacting to things that don't actually pose a threat.

That's often how people describe Rejection Sensitive Dysphoria, or RSD.

The name can make it sound as though we're talking about huge life events, but that's not usually what people tell me about. More often it's the little things. A colleague walks past without saying hello. Someone's tone sounds slightly different. A friend cancels because they're tired. A manager suggests changing one sentence in a report.

Objectively, none of those things mean rejection.

Emotionally, they can feel enormous.

I sometimes wonder whether that's why so many people become people pleasers without even realising it. If your brain is constantly scanning for signs that you've upset someone, it makes perfect sense that you'd try incredibly hard to keep everybody happy. You apologise when you haven't done anything wrong. You say yes when you really mean no. You spend so much time worrying about disappointing other people that you end up disappointing yourself instead.

What makes it even harder is that people are often incredibly unkind to themselves afterwards.

Why am I so sensitive?

Why can't I just let things go?

As though criticising yourself is somehow going to switch those feelings off.

It rarely does.

One of the most helpful things I've learnt, both professionally and personally, is that our brains are brilliant storytellers.

The trouble is, they don't always write fiction labels on the stories they create.

If somebody doesn't reply, our brain fills in the gaps.

If somebody looks distracted, our brain fills in the gaps.

If somebody says, Can we have a chat later? ...well, most of us have probably planned our own disciplinary hearing before lunchtime.

The difficulty is that our brains usually fill those gaps with fear rather than facts.

I've found that simply asking myself, What do I actually know?, can be surprisingly grounding.

Not what have I imagined?

Not what am I worried might be true?

Just... what do I actually know?

It's such a small question, but it gently nudges the brain back towards reality instead of letting it disappear down a rabbit hole of assumptions.

I also think it's worth remembering that we're simply not the main character in everybody else's day. That sounds harsher than I mean it to, but I actually find it quite comforting. The colleague who seemed abrupt might have had a difficult morning. The friend who hasn't replied might have left their phone upstairs. The person who looked unhappy might have been worrying about something that has absolutely nothing to do with us.

We tend to assume we're being judged far more than we actually are.

If you've recognised yourself while reading this, I hope one thing stands out above everything else.

You are not broken.

You're not weak.

You're certainly not too much.

Your brain is simply trying a little too hard to protect you from something it believes might hurt.

And whilst that can feel overwhelming, it doesn't have to stay that way.

Understanding what's happening is often the first moment people stop fighting themselves.

Sometimes that's where things begin to change.
