School bullying can be a no-win situation sometimes.
Have you informed a school counselor or mentor about the bullying issues? Schools have got a lot better in responding to this and that it is unacceptable behaviour, so if you haven't bought it up, you may consider doing so.
If you're in special education it can be easier to spend your time there, with the aides and so on and away from the student body, but if you're in general population it's tougher.
I didn't have much self or social awareness at that age so I didn't understand bullying if it was targeted at me, but in a sense I did just "disappear" anyway - I was perfectly fine with spending my time alone, exploring bits and pieces of the school yard, playing with the textures of things, climbing on the fire escapes and trees to read my books, sneaking into the music quarters and playing with the instruments, or just wandering around.
No one can bully you if there's nobody there.
You shouldn't have to hate yourself just because others don't understand. It's just them - they don't understand.
