Everything is wrong and I don't know how to fix it?

ever since 7th grade my life has been a downwards spiral. first my grandma went into a coma but we all thought she would pull through. I mean it was grandma. she has grandkids and great grand kids. a couple weeks after she died, my dog got out of our fence and chased a car and got hit and killed. I know it's not 'omg go get therapy' but it was the start of death and everything else. 2 weeks later my grandma died. the 3 weeks later my brothers best friend died. soon I was like WTH what Is going on! then my bestfriend Abby started dissing me by telling me off in front of her friends, said she didn't want to go to the mall with me because I was to embarassing. an I really needed her but she wasn't there So I told her just to leave me alone. I started making stupid mistakes everyone makes, but because I'm in a tiny school it's worse. I was almost arrested. I tried to punch a girl I barley knew for something so stupid. I was threatend with suspenion for something I didn't do. and I started flunking a couple of my classes because it seemed life was kinda fall apart around me. I didn't really have anyone to turn to for alot of things. my friends and the whole school started calling me stupid and I somehow got this reputation that I was stupid and some bad *** chick when I really am not. i went into a mini depression thing. I didn't realize it but I did. and I stopped talking to my friends that made me feel like crap and was left with one friend. I couldn't catch up on school work. and I stopped talking to my parents and stopped wanting to go out an started eating less. there were times when i thought suicide or cutting myself. I asked my counsler for help but just told me to focus on school and I was like there is more to life than just school. so I asked my mom to send me to a counsler but she never called. then in 8th grade this new kid named sam came. and I thought new year new me. so I started hanging out with sam. we became really good friends and almost something more. but then I over heard someone telling him all the things I did in my pass and then some rumors that fit so nicely with other rumors that some people just had to believe. so insted of Hannah, the girl he had gotten to know over 4 months I was now this Hannah that some random person told him about. soon he became more distant and soon just left me in the lurch. I then went into my second depression and this time I relaized it, but no one else did. and if they did notice, the didn't ask about it or help me. I started weighting poetry in a notebook but iblefted it in a classroom on accident one day and people started reading it and saw my deepest tjoughts and everything. yet they still didn't do anything but pick on me because of what I had written down. I've tried multiple times to get friends help and my moms help but none of them ever seemed to care. sorry for any misspelling. I'm on my iPod.
