need help

I can't speak to people. As in, I don't want to see or be around other people. I can't relate to anyone around me either. People tell me they have all these issues in their life and I just go, "So what?". I have a lot of personal family issues in my life ranging from being raised in an abusive environment and some degree of sexual misconduct from older people and whenever I speak to other people, I'm always hovering between diminishing my own struggles and looking down at what other people define as struggles. I don't hate that they are more fortunate, I hate how they complain whilst still being more fortunate. And people like say, "you can't compare suffering", and like idk whenever I hear that I just get annoyed and it makes me want to ignore people more. It's reached a point where someone can say hi to me and I just wish they didn't. I don't really want to go outside, I don't want to go watch movies with other people, and I don't want to make friends or speak to anyone irl anymore. I'd rather write fanfiction, play games, study, and live by myself in a small apartment. idk what to do, and I don't really want to find a therapist because that's just another person to handle. idk if I should get this cured, but my mom has been asking me if need a therapist for such a long time (since six years ago when I was 11-12 because that's when this sort of started). I don't really see the point to getting 'cured' honestly.

like I can talk to be ppl and get happy about it and stuff, but like, after a while I just get sick of them and want to leave but it's rude and yeah.

idk what to do about it.
