Wow! you sound a lot like my daughter and your situation is very similar. Have you looked into St John's college? Since you have to get a bachelor's to move on anyway, it may be just the thing, four years of real critical thinking and exercising your brain surrounded by other independent thinkers as opposed to boring yourself to tears.

My daughter would just as soon test out of college if she could - that might be another option, see how many CLEP exams you can take to just get through it as quickly as possible.
Good luck!
