Hi Ki3, is it possible for you to take some or all of your high school classes online? I have a cousin who is autistic, so even though he is very intelligent, he has a lot of social awkwardness too and a very hard time making friends or fitting in to a normal school setting. When he started high school a couple years ago, he and his parents decided that it would be better for him to take online classes, and so far that's worked out really well. He does have to go to school once per week, to take tests and things like that, but the rest of the week he's online.
Other than that, I just have to agree with what NGNG said - high school can be a really rough time for a lot of people, but once its over with, it really can and does get better.
