Tired and weary...

My father-in-law is going through treatment right now for prostate cancer. He is having a pretty rough time of it and has us all worried. He already had so many health problems that having cancer is like the icing on the cake. The poor guy has diabetes and other problems that make him need to wear something like activa compression stockings. He is now walking with a cane and has trouble navigating without pain. I wish there were something we could do to improve one aspect of his life but it just seems to all be beyond the scope of what anyone can do.
