Please help me,im seriously damaged

its not a proud thing to do.or say and im not lapping this up or trying to be bigheaded of saying this.but I know you cant help me advise me the correct ways but your thoughts would count. I went to the doctor a month ago to see if had bipolar [ im only 16 - and my friend said something was seriously rong with me] and he just laughed in my face [ but when I go to the doctor im quiet because why would you go in there and start talking to a doctor right]. so I’ve been sexually abused by my dad - but that has nothing to do with that. but I was excluded for a week for going physco for no reason,like throwng the chairs breaking a glass pot,kicking and ripping plants to shreds and damadging a clock and smart board in the process,and hit a teacher.but these are many of few outbursts I had during life. when my mum shouts at me I cry very easilly.but when at school I have theese mad ideas in my head I become obsessed easilly over guys and plans [ I.e go on holiday,get a kid,buy a monkey and that]. im fully aware of what I do but when im in a rage mind I cant control and since im having the fun of playing with a lighter [ I nearly set fire to the school toielts as I had a crave to light tissue paper while my friend was in the cubicle.but I set my room alite when I get angry which cools me down and then I out whateva I have burned.I have told my family but they dont belive me and just say im weird.conselling NO.and the only ones who seem to understand is my friends,and sometimes if I crave love I will go running to a guy who wants to use me for sex and then my friends turn on me what can I do
