Should I be 'unschooled'?

I am 13 and about to be in 8th Grade. I've missed at least fifty days of school, causing me to have at home summer school (work packets, emails, conference check - ups,etc.) The teachers talk about me to other students saying I " only come for the good things", or they " don't believe I have any real problems and just don't want to come". It really hurt my feelings for them to do this, and they already made me go through counseling ( the therapist called me a liar ), and they said the least I could do was pick up my homework. My mother has tried to, but the office would say there was no point. I would then be yelled at by my teachers when I went back, and people would scold me and interrogate me for not being there. I dont know if my OCD or Schitzophrenia come in play with any of this, perhaps someone out there knows? I am also one of the smartest kids in my school, yet they say no matter what I have summer school in eighth grade too? I cant quite comprehend this, and it makes me feel very bedlamite. My dad doesn't like the idea, but he doesn't know half of my life, because his inactivity in it. Does anyone believe this is a better path for me given my current situation?
