Dvd, I know that sometimes we all have doubts about getting through treatments. I too do not have the physical strength I used to. When I was first diagnosed we owned a horse farm that I used to do 40 to 60 hours a week of hard physical labor in addition to my normal full time job, so I was very busy. Due to my cancer we had to sell the farm. SoIunderstand how not being able to do the physical things makes you feel.
Have you tried physical therapy? I have used physicalb therapy to help with muscle pain and weakness. They can show you exercises that will help you feel better and do more. They are trained to work with people that have had physical issues. After I recover from my surgery next week I will be going back to physical therapy for my back whichseems to hurt alot and is weak. I expect they will be able to help me become more active. I think it could help you too. Good luck.
