Thanks for your lovely words of support Karen. I have now looked into the idea of yoga as you suggested and it looks like there is a local group I can join on fridays, not specifically for cancer patients but says all are welcome so I'll give it a go!
You are right, one of the hardest things for me is that often (except during chemo of course) I don't feel sick. If I put a wig and makeup on, I don't really look too sick either. So when I go out people think I'm all ok and then wonder why I get so tired etc. They don't understand the muscle loss or aches and pains I have underneath! I'm used to putting on the brave face and pretending it's all ok but at the end of the day without all the gear on, i'm faced with the real me in the mirror and it's the constant reminder of what i'm going through that I can't escape from.
I am working hard on trying to see the beauty within and understanding that (hopefully) after surgery I am cancer free and it's just the treatments that are still making me feel sick as you say. Hearing it from others does make it much easier so thank you once again! :)
