I feel like I'm going crazy?

I feel like crying all of the time, its so annoying, i want to do anything to kill time because i am so bored. I have like 1 friend who i can't stand and my family is just annoying. My mom is always putting me down, my sister couldn't give a crap about me and my dad isn't there. I just feel like i am breaking down, i am so empty inside i feel like i don't know who i am anymore. I am on 10 mgs of busparone for anxiety when i was on lexapro i was having reverse effects of depression. I am 15, a really nice person and i got to a school with all mean people no exaggerations necesary. I also volunteer and am a really good person, i just don't know what to think anymore.
