I so agree with you on the positive attitude Louise. It's not always the way I have felt, but it has been for the most part, and I agree it makes you feel better, cope better. On the down side of being positive ;-)....I remained so active during my chemo (four rounds of AC, last one yesterday yay!), the drop offs of pre-cooked meals stopped after round one when friends saw I was down the pool, doing laps, the day after my first round :-).
But having written the above, we are all hard wired differently, and for some being and staying positive is a harder road to stick to, especially when dealing with depression, on top of diagnosis, treatment and all the side effect joys that can bring.
I just hope for everyone there comes a time when they feel the can breathe, and move on, happy in themselves again.
