All Friends I've Had Dislike Me

Non Indepth Questions :
1. How do i stop complaining all the time? (its like It's a natural thing that just happens now)
2. Why do all my mates always chat shit about me?

More Indepth Backstory :
Basically Since I was young I was around a bunch of idiots who were always toxic to eachother. I got used to it and now Just complain about anything and everything without even realising Im complaing.
Any friends I've had have always just started chatting shit out of nowhere which happens a few months into friendship. Usually its fine before then. I don't know what to do because it happens no matter how many times I get new friends. So "get new friends" is not an option.
