Emotionally Unhealthy?

im only in 7th grade but i feel very emotionally unhealthy. I have gone through my mom having cervical cancer to me having a deadly melanoma to my parents divorce to my mom getting engaged then my stepsister getting Leukemia and my mom and Aaron filing for Bankruptcy then we bought a new house and i had to start a new school which hurt me since i didnt fit in..then in 2009 just recently my moms fiance for 3 years (since they couldnt pay for the wedding just then) left us and we are not allowed to have any contact with him since he just for some reason got married to someone he knew for 6 monthss in february...i may not ever see my stepbrother and stepsister again and i still call them that since it would sound weird saying ex step...i have trouble speaking my feelings now and i just bottle up problems and hide them..now i barely feel like my friends actually like me and my mom is just starting to get healthy from being in the hospital with bronchitis and plus we just had the worst year since there was no aaron or kids this christmas...i cant really let go of my past and just wish i wasnt alive i was cutting my wrist but i noticed how stupid that was after two weeks...i might even have another Melanoma again..dont you find that i have a emotional problem i cant find anyone to talk to that i want to since i f idid i would be in tears i cant seem to be friends with girls and actually believe we are friends..and no its not just drama this has been going on since 2nd grade for me maybe thats why im a little heavier since i was never chubby in 2nd grade which im not now just a little over weight i always seem happy to people and try to cover it up but i dont want to....its not me being a teenager for sure i just need to know if im in some emotional unhealthy state thanks :)
