I know that everyone hates me
Surely not everyone. What gives you that impression?
If they don't hate me then why do they treat me like literal garbage?
Everyone you've ever met treats you poorly? Maybe just forgive and forget. Or you could ignore them.
Nah, people can be a little nicer.
I do agree with you, but I don't think everyone hates you and I don't think you should feel that way.
