How do I deal with being misdiagnosed?

My doctor made me worse then I seemed when they did psychological testing on me making me seem worse then I am. Is it illegal for them to misinterpret the results to make me worse than I am because there is no way it’s accurate! What should I do about this because my life is ruined now with people treating me differently. I shouldn’t be treated like this. What rights do I have?
