HELPP PLEASE!! NEED ADVICE!

So last year I went through drespression and my boyfriend of a year broke up with me when I was going through all this and my mom kicked me out bc she couldn't handle her only girl and "perfect daughter" to go though something like this. I had it all cheerleader and VB player a lot friends and volunteered some weekends and did very well in school so she kicked me out bc she said I was causing to much stress on the family so I went to live with a best friend and then later left that house bc all she does is smoke and do drugs and I'm not into that so they came up with a plan to kick me out. So they stole there grandmothers phone and then said I did it and there mom kicked me out later the mom found out wasn't me and aplologized. Then I moved in with my boyfriend that I knew since 6grade so about 7 years now and we were friends before that and only dated a month and half and then moved in together. Now it's to the point we're feelings are lost and I just want to move out and be able fate other guys and kind of enjoy my last year of high school without feeling like I'm married and my life is over. We constantly fight and it's over stupid things. I could move I. With my dad but he's a druggie and it's not best for my situation I think and it's in a different state and I moved about 5 times my 2nd semester of junior year in high school so I'm tired of moving I just don't know what to do. No one understand that I don't have that mother figure and I want one but just can't seem to find someone to talk to 24/7 and tell my problems too and them give great advice. Plus my moms not talking to me or my step dad or my 2 younger brothers so I feel really alone and I hate that no one understands bc this only 1/3 of the story. Please give me your input. Sorry that it's long..
