I'm not a survivor myself but I was doing some research on cancer, I found this really good website where cancer survivors can talk to people who have also survived cancer. Its a bit like bebo and facebook, you make yourself a profile and then you can write comments to different people on it and also write blogs etc. It is specially designed for teenagers..I really hope that it will help,
