I need advice

I have pretty bad depression and my best friend is leaving me because it has gotten so bad he can't handle it anymore it just gives him to much stress cause he's always worried about me and I think my boyfriend may also be leaving because he's been ignoring me and we haven't talked much lately and I really just don't know what to do. My mom is mentally abusive and my dad is mentally and physically abusive and there's so many rumors about me at school and I don't have any friends left so can anyone give me advise I still have about three and a half years until I can move out.
