It might have been an anxiety attack. I want to say you are obviously a very intelligent and talented individual. Your painting was awsome. I always wished I could draw or paint but my talents ran in a different direction. I wish your parents were more supportive so you would get some help in dealing with stuff.

Since you have to deal without the support of your parents and help from a therapist you need to develop another support system or two which you have started by posting here. You are also reading up and learning how to deal with your depression and anxiety.

The main thing I wanted to say is I think you are a very strong, intelligent, creative person you just need to believe it. You have to stop putting so much pressure on yourself. I get the need to perfect especially when that is what is expected of you by others. I've been there. Please hang in there, I know it doesn't seem that way but things will get better eventually.

Take care of yourself
