First off tell your son he is not alone. Most players at some point in their careers go through this to varying degrees. As a parent you must show confidence in your son that over time he will be just fine. Someone needs to believe in him. Tell your son you are there for him to help find a solution, that he can confide in you his thoughts and feelings as he goes through this. It is not easy for anyone who goes through this. It is imperative for your son to be around positive people/coaches during this time. I wish I had a magic answer for you. Stay positive, know that it will get better and he will be a stronger person after overcoming this. Keep us posted.
