How do I stop hating my life and myself?

I`m 16 and I hate myself I really do I hate how I make mistakes, how I look, how I hate others because I hate myself. I have a hard time looking at myself in the mirror I consider myself to be very homely looking but my family and their friends say differently. I have 3 friends my cousin, the neighbor who does not consider me a friend but more like a sister whom he has no choice but to be nice to and my boyfriend who I agreed to date because I felt guilty and now I feel too guilty to dump him. My mom is often depressed and sometimes threatens to take her own life she is very controlling over what I wear how I do my hair and other things that should be my concern not hers if I don`t do things her way she will be a ***** til I give in to her she also manipulates me by telling me i`m grouchy.sad until I feel that way when it`s actually her that feels like that.Both my sisters have bipolar and hate me one day and love me the next they both hurt me so much I don`t really like to consider them family. I have OCD, social anxiety and struggle with an eating disorder (I still limit what I eat even though now i`m a healthy size). I have been struggling with my life for 4 years now. I see a doctor and a therapist and am on medication thay all help as much as they can but I still feel like I want to kill myself and just escape life. please help.
