The art course is a little ways away but I think it could be really fun and productive to help with self esteem and just emotions in general. I paint sometimes. I need to paint more but I don't know, I just don't. It does help get emotions out though.
Definitely look for a therapist but hold out for the right one. You don't need someone to talk about their family and vacation. That would annoy me anyway. You are worth finding the right therapist. It just takes time and patience.
Hang in there buddy. Kit
