Oh Boy! I agree with Robyn about your surgeon! I also think it helps to write down what you do exercise wise. Give yourself a pat on the back for everything you achieve and maybe a little reward every now and then too. I bet you will find that your family will notice the little changes and this helps you to feel better too.
Think of your exercise as a positive thing (do what you enjoy rather than forcing yourself to do something too difficult). Maybe use music to motivate yourself too. I found this worked wonders for me. Sometimes the words of some songs would actually make me cry but they also helped me to feel stronger.
I also went to a physio who specialized in helping people who have had Cancer. She became my own personal cheer squad and really helped me to notice every improvement I made. You can see your GP who can fill out a form (I forget what it is called) that gives you 5 subsidized visits to a physio or exercise physiologist through Medicare. Good luck and let us know how you go. Deanne xxx
