What a great idea! When I was diagnosed (Stage 3 ER+ IDC, May 2013, aged 40, with 3 young children) none of my medical team gave me any hope. When I tried to get them to say anything positive they just shrugged or said "take one day at a time." This made me more scared than anything else, as I felt that if they didn't see any hope then there was none. I searched hard for hope and inspiration, finding it on this site and in books. However, it took me months to fully feel in my heart that there was any hope, and during this time I was incredibly anxious and I imagine that as a result it was hard for my body to heal. Since finding hope I have worked hard, through diet, exercise and meditation, to regain my health and at the moment I feel really well. If I had been given a book at the start like you are suggesting it would have helped me enormously and saved a lot of time!
I don't think I'm far enough on from dx to give hope to others yet - when I was diagnosed I wanted to hear from people a lot further on than me . Have you thought of pm-ing any of the women who have posted their stories in this section of the forum (5 years on etc)? They might be willing to help.
On a personal level, if you find reading inspirational stories helpful I would recommend a book called "Radical Remissions: Surviving Cancer Against All Odds" by Dr Kelly Turner. I have recommended it elsewhere on this section of the forum - it really does give hope for healing with cancer at any stage.
Wishing you all the very best in your mission to spread hope!
I think it is a brilliant idea and good luck to you. I wish it had been there for me when I was diagnosed - there were plenty of negative scare stories out there but very few hopeful ones.
