I always say that i wanna go home even though iam home. help?

ok let me start from the beginning. my dad used to smoke and was an alcoholic and he would just flaunt ladies that he cheated with in front of my mom's face. so they got a divorce(separation really). and then my fam - my dad moved to MI from GA and i hate it here but we moved with my aunt and then they got in a fight so we moved to my other aunt's house and tomorrow is the last day we have here and thn we're movin wit my gma who is most likely gonna kick us out in at most 2 weeks(she treated my mom aunts and uncle terribly as kids) anyway im really troubled and im totally stressed and no one understands me and i just keep a distance from everyone because im crazy and i have anger issues. and half of my day im really depressed and the other half im really happy and i have mixed emotions 24/7/365 and i have alot of thoughts of cutting myself and my friends aren't deep enough to understand me, not even my best friends but one of them is but when i try to talk to her about it she never listens and gets mad at me for it but there's no one at my school that would ever understand not even my boyfriend who by the way is known for going with girls for no reason but everyone thinks he's for real about me (including me). when im outside or i go to the mall or the store or something im kinda happy but when im home i always blurt out saying i wanna go home. please help me! i need it!
