): i am suicidal and depressed and dad wants to leave my mom. ): please read. and answer(or comment) ):?

my dad has been deployed 3 or 4 times to iraq. he has been back home for over 10 months. my family consists of me im 16, my sister she's 12, my mom, & my dad. so to start off when i was little i was basically accident prone; 12 broken bones and 2 head injuries. i major head injury was when i was in 3rd grade, i was a good student and a good kid i was more advanced than any other kid my age. but in 3rd grade i had a series of stuff happen in a time span of 3 weeks; 1: i had brain surgery, 2: my uncle past's away, 3: while at his funeral our house was being robbed. so brain surgery seems to has caused some damage to me, never made A's and B's again after 3rd grade, behavior, etc. so a couple of years later i seem to notice some depressing stuff. i have been admitted to the hospital for trying to commit suicide 1 time, i have tried committing suicide i think 2 or 3 times. i firstly tried to commit suicide by rapping tape around my face and head because family issues, secondly i tried to commit suicide by hanging myself because family started not loving me and appreciating me example: my sister spit in my face. i still have had many many suicide thoughts but never acted on them. i am seeing councilor for about 2-3 years now. i have been slapped, and pushed, and i think even punched, spit on by sister and dad, choked, hair pulled, ed, etc. (and one time my dad made me do wall sits for 10 min and every time i fell i got ed or slapped or punched.) these at one point in my life around from when my dad got home from iraq to about the middle of summer 2010 happened every day. i will admit that about 1-4 days of this was because of drugs :( it was a new thing i tried and have never done. i hit a point were i was just bad. i did pot, sold pot, and even tried to grow it. and every time got caught. but that was for a good 2-4 week thing i no longer am ociated with that stuff any more. (: but now present day i am a sopre in high school i now am getting in trouble for not taking my medicine, not taking protein, not working out. and so now on my moms birthday my sister dad and i all planned on all getting her a card and an hour back mage so we did. but i after school that day though i would buy my mom a present from me, just me i though it would be fine and nice because i though now that i have a job i could maybe show her i care by using my money that i worked for to buy her a gift. and i got in trouble by my dad for doing that, my mom thought it was very nice. but i think the most ****** up thing is that its my moms birthday on this day and my dad says he is going to divorce her if the stuff with me continues! my mom asks well what is he doing that is so bad to divorce me? he is doing fine he has A's and B's for the first time in 7 years. hes doing good hes not breaking the law hes not bad and teachers say nothing bad about him. my dad says well it just he hasn't took his medicine in the past 3 days and has been talking back. my mom says ok he has maybe not tooken his medicine but thats something to talk to him about and i dont see him back talking you ever! so eventually i say to him "basically telling him i am depressed and suicidal" saying ok well if its all my fault im driving you crazy and to divorce mom, then i might as well say it your driving me crazy to kill myself. anyways sorry for getting off topic at my moms birthday dinner theres my mom, my dad, my sister, my grandma, my grandpa, and i, so my sister is over here eating her steak like a caveman or something and my mom gets on to her, but my dad on the other hand is over there laughing at her, encouraging her. then shes throwing rolls at my grandpa again my dads laughing encouraging her on again, my mom gets on to her, i then texted my mom secretly saying if i did that i dad wouldve gotten on to me. later on that night my mom tells my dad what i said and he says well you treat another kid better when the other has been in trouble before. but anyways i was wondering what someone else out there in the world thought about life. if you have any commits or suggestions on my life please do write them. i need all the help i can get. thanks
