She hates me and I feel so bad?

So I was friends with this girl from school not great friends but we talked once in a while. I wound up pushing her away and being mean because of my mental disorder which I tried to apologize and she knows I'm in therapy for. I apologized and I think she still hates me. This is the fifteenth friendship I've broken in the past 3 years. I try so hard to work on things from therapy and be a good person and I always mess up. What can I do?
