Get your son to a therapist as quickly as possible...try to find someone who specializes in anxiety or phobias. You are a wonderful mother who seems quite knowledgeable. I am 40 and have lived with this on and off, and also with generalized anxiety, and I live a mostly very happy and productive life thanks to appropriate therapy. Now I think my 6 year-old daughter is starting to show signs, and I will get her into therapy as soon as it seems necessary. I wish you and your son luck.
