I just want to echo your story because it is almost identical to mine (right down to the incorrect diagnoses). I was bullied to the point where I developed a colossal thrombosis in my arm. We had no idea until I was 16, which is when my parents became aware of these types of issues.

I was lucky enough to get off the meds extremely quickly (2 weeks as I recall, I told my mother I hated them - she took me off after noticing how lifeless they made me). I was lucky enough to move countries, to a new school with fresh schoolmates and friends - somehow a school with the most beautifully accepting people you've ever met. With just that one chance that "normal" people gave me, I turned completely and you simply wouldn't believe that I am autistic today.

I've overcome a lot less than you and I am proud of it, I can't imagine how proud you must be.
