I agree with Nadine....do what YOU are able to...don't compare yourself to others....good lord if we did that i'd be running a marathon while cooking gourmet dinners for the community!
I am yet to get back to anything meaningful as i have been hit with one treatment after another ( only ever a week in between each starting!) and now have just had my double mastectomy...I'm on my third week since surgery and only now feel as though I can go for a walk down the street....
Set yourself realistic goals and once you have accomplished them, move up....best wishes
