I'm different in that I'm not afraid of conflict, but I definitely do read every interaction I have with other people through a framework of them trying to subtly tell me they don't like me/are criticising me.
Mine's come about through a combination of genes, the way my mum taught me to find something to critisise in every situation so she could feel superior, and being bullied/isolated/excluded from 3 YO until I left school.
It's so easy to say to rise above it, find the positives in your life, think about things from a different angle (absolutely no offense to your lovely post Majestic), but some things are so ingrained that they become a part of you.
You can pretend it's all different when you're feeling a bit stronger than the norm, but as soon as something shakes that, you're back to square one and feeling twice as shit because you feel you've let yourself down.
I've found accepting who/how I am is the way to go. It might not be what's expected, but I can only work with what I have. I'm not saying that my solution is for anyone else, but I actively avoid other people and I can go a couple of days at a time now without freaking out big style with anxiety.
I was only seeing other people because I thought it was proof there was something wrong with me if I didn't want to, but it made me ill.
In the same way that it's not the person who has a disability who is the problem it's the way society reacts to their disability (steps not ramps etc), it's not that you have to strive to be similar to someone who doesn't have MH problems (or able bodied), but you should look at who you are realistically and do what suits you rather than what's expected of you.
Soz about essay, probably doesn't make sense/apply to you/is relevant in any way/wish I hadn't said anything now/you're going to think I'm judging you harshly/you'd hate me anyway/now I've gone on too long and losing any confidence I had
