Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. You son is not necessarily having any phobia. But he may be a victim of anxiety disorders. Why this is happening, we should investigate this. Now a days every school has the services of a school counselor. Take his service. Or talk to your child s teaches / teachers. Understand the pattern and moreover understand your son. Then take him to a psychological counselor who should be of help to overcome the problem. Please do not take your son to a psychiatrist before a visit to a psychologist. OR You can post a direct question to me in this website. Include every detail as much as you can. I shall prescribe some psychotherapy techniques to control your condition. I am sure that the techniques should be a success. Hope this answers your query. Available for further clarifications. Good luck.
