write or wrong- im sorry for what you, your family, and your son must be going through. honestly i think the first step is to go to a rav and ask the rav if he suggests a therapist. many times there are deeper things behind a child going off and many times its just out of confusion. but none of us really know because we dont know your child. a rav will be able to help you decide where to go from here and how to approach your son. all of us who are replying are just giving our own personal advice while a rav will be able to guide you towards the decisions that are best in your scenerio.
