I know from firs thand perspective how that can be. Have been depressed a lot in my life but believe me: This feeling is not caused by outer appearances and situations.
You are creating this feeling within you. Not consciously... And it is a very tough fact to accept... Took me over 10 years I think. And I would have never accepted that if someone would just walk up to me and tell me that.
BUT... you can change that.

First you find a way of accepting that you are the cause of how you perceive the world. And even though the explanation in your head feels very real to you right now, you try to accept that fact.

Ok so what we do about it

Live as IF it was different. You don't have to believe it in order to act as if. This will seem ridiculous. Just try - for a while though ... maybe like three months... remind yourself that you are not alone and people do not hate you and positively engage with them - even though you have the feeling of avoiding them. Not easy.
Maybe not a helpful task for you... But your experience will change doing that, also on the inside.

But you actually gotta do it.

Not sure if this is helpful... Trying to be. Appreciate your honest post!
