I'm sorry to hear you have to deal with this. I understand not wanting to tell your doctor. It phsycially hurts to even come close with my doctor. I feel like I'm having a heart attack. But its also easy for me to tell you to tell your doctor because I do want to see you get better and despite the intial weridness you feel when you admit something to your therapist I think it feels more "undirty" after you've talked about it. I don't think your therapist will consider anything you have to say as "bad" or "good". People have manys sides to them. Its just not that black and white. Hopefully, not only does your doctor have a good educational background but I've come to find that most of them have really thought out philosophizes (sorry my spelling sucks). I hope my two cents helps!
