Digtexas,
I'm sorry to hear that you weren't prepared for the recovery period. As Kim said (depending on you as an individual), it will take about 6 months for that feeling of being human again.
There are two things about cancer and it's treatment that some people don't understand. The first is that this is all cumulative and you get to a point where you feel you've hit a "brick wall" - literally. You can't expect to bounce right back. The second is that we take some basics about our bodies for granted. But when it is assaulted by foreign toxins and radiation at a level our bodies don't take kindly to - our bodies don't function as they would normally. My mother has learned the hard way how being dehydrated can affect so many things.
I'm with Kim - go easy on yourself. If ever there is a time for one to be selfish - this is it. Concentrate on yourself and doing things to help your body recover. Even if it means sleeping. It's your body's way of helping you to heal.
Best wishes,
Cynthia
