Fear and Need for Control

I realize that I have a lot of fear and need for control over my 12 year old son. I worry about how he will “turn out” or that something bad might happen to him. Therefore, I try to maintain control over him and that often leads to disharmony. I would like someone to tell me that it is not my job to control my son and I have no control over how he “turns out”. If I believe that, maybe I can feel free.
