Attorney Cherniack said it best. The short answer is no. Would or could your parents claim that you are unable to make prudent decisions for yourself due to your diagnosis? Would they attempt to seek guardianship over you? A choice to drop out of school if you are close to graduating would be a choice they and the Court would likely view with trepidation.
I do hope that you intend to finish your high school education. You will have a much harder time getting your GED or high school diploma later in your life than you will now.
I wish you the best of luck.
