I hope that when you go to your therapist, that you will be 100% honest with him/her, and admit to your part of the relationship with your son. Everything is not 100% his fault. Therapy is hard work. Your therapist is going to make you hold up a virtual mirror to yourself, and make you take a good, long hard look at yourself, and your actions.
A therapist isn't there to hold your hand, and to say, "There, there. Poor baby".
If you think that's what the therapist is going to do, you will be in for quite a surprise. And when the therapist does make you look at your own actions in your relationship with your son, I just hope that you don't bale, simply because the therapist isn't offering you tea and sympathy. I hope that you stick with it, no matter how difficult it gets. It's a therapist job to challenge you, not to pat your hand and say, "Awww, poor baby".
