I have a boyfriend who has just been diagosted with PANDAS, and the worst part about it is his OCD and anxiety. He has terriable serperation anxiety and when i'm away he has some weird kind of tics. I just want to know how to help and communicate with him about issues with him getting flustered and being so nit picky. Does anyone know anyways I can help to understand him or help him so he can control it instead of it controlling him?
