I just want to be happy for once!!

So, I moved to Washington about 12 months ago, I thought I was finally getting a break in life, I was happy, I had a lot of friends, I never herd a rumor about me, I was happy and depressed simultaneously. The thing is, is when I was at school I was the happiest kiddo alive (I know your thinking whats the problem then?!) But when I would go home I would just feel like I was sh*t, worthless, a waste because everyone in that house (My mother, my step-dad whom I call the STD, and my big sister) told me I was,but not in actual words. So after 10 monthes of living there I fell in love blah blah didn’t work out cause my mom tore us apart (everything happens for a reason) So after we broke up my mom never trusted me alone with my friends so I was always at my own house, and people in the house would not shut up about things I’m always doing wrong!!! So they put me on meds, turns out the meds were making me suicidal and I tried to commit suicide (swallowing a whole bottle of medication) My aunty found me and took me to the hospital and after I was “saved” (stomach pumped, drank tarr,I.v sheeut) things stared to get normal again, my mom gave me back alll my privileges (a phone,going to friends house,dating,going to the mall ect.) and to celebrate I had one of my friends come over and then after she spent the night we went to go spend the night at her house, and my mom randomly showed up on her door step and told me she had a surprise for me and that I needed to come with her (I HAD A TERRIBLE FEELING) she asked me to get in the car and I asked why we just took the seatac exit…She said she bought me a plane ticket to visit my real dad whom I had just moved from in hawaii. I was exited until I got to hawaii and my dad told me I was never able to go home to my mom…She tricked me. So now I here in the place that makes me miserable…I ABSOLUTELY HATE THIS ISLAND!!! Soo…any suggestions to maintain my sanity?!.
