Hi Doctor, Although I Dont Know Where To Start Asking

Hi doctor,
Although i dont know where to start asking questions. getting straight to the point doctor,
i have a bringing up in a very negative and drastic environment , parental abuse, had many rough relationships , out of which one committed a suicide, and the last one ended so dramatically that i had to do time in jail for 6 months for false acquisitions. Have tried killing myself several times. But all half hearted attempts knowing that they'll hhurt me not kill me.
i dont know doctor what exactly is happening to me, but i know that my condition is very fragile. have anger issues. a lot. and in seek of help.
i have not asked any question though instead have told you the jist of my condition .

so .. what can be done ?
