What to do about phobic parents?

Ok, I've fallen in love with this girl named Maya. We've kept our relationship private, but recently, someone leaked a photo of us kissing in a photo booth all over school. My parents saw, and now they're appalled. They hadnt even wanted to me to be just FRIENDS with her because she was black, and now this. They tried putting me in this gay reform program, and I reluctantly agreed, because they said if I didnt do this, they'd send me to live with my terrible aunt and uncle. This was my first girlfriend, and I've always been in denial that I liked girls. I thought maybe I could change, and that what i was doing wasnt wrong, so I broke up with Maya. Then, the other night I wenti ice skating with myy sponser from the reformation program, where she ran into her old girlfriend. Let's just say by the end of the night I caught them going at it. MY sponser said that maybe we couldnt change. I knew id made a mistake, so i went to a party I knew Maya was at. I told her everything, and we made up. But, someone called my mom (supposedly the same person that leaked the picture) and told her we were there together, holding hands. She sped to the party and drove me home, saying that im not her daughter anymore. just because im different. and now, im in the airport in my aunt and uncle's hometown, waiting for them to pick me up. what should i do? im 16, so can i sue? please help!
