I have never been one to have counselling but I did go to see the psychologist at Peter Mac before my final decision on having a double mastectomy. I was quite nervous at first but after a few minutes, I was talking to her like an old friend. Things came out that I had bottled up in side, including anger and the 'why me' feelings. I think talking to a professional trained in this area helped me to not feel guilty about my anger and fears and to try and let them go. I haven't always been successful but I'm getting there.
The Cancer Council might be a good place to start as Paula said and as Deanne said, you are certainly not alone.
Best wishes
