When I hear about an anxiety syndrome I don’t have, my anxiety kicks in

I feel like I have lied to everyone else and myself, cause I don’t relate to some posts here.

Like, when I see someone saying that they almost puke when doing anything socially, I question myself.

Cause I don’t get that extreme of symptoms. I mostly start hating myself when I feel like I did something wrong. People don’t even have to look at me weirdly to make me feel like shit. Cause just being social (doesn’t include going for a walk when people see me. It’s mostly if I have a discussion with someone, or just talk) makes me hate myself more every second.

Does anyone else get this, and how can I stop it?
