Thanks a lot for your reply Sam2.
We found the first therapist for him through our physician. He also prescribed medication for my brother, but he doesn't want to use any, and I agree with him. Those pills got nasty side effects and I don't want him to be dependent on pills, neither does he.
His study is already making it worse, since he's busy with his 3rd year but he still has to pass the subjects of the first year. And he still can't manage to pass them. It really just makes him feel worse.
Thanks again for the reply.
