I agree about the walking. Even a short walk in the fresh air might help. If you are in bed alot there are bed exercises you can do to keep your bones, muscles and energy at reasonable levels.
You might also want to consider asking your doctor to check your B 12 levels. Low B12 can contribute to fatique. Your doctor can add a test for B12
on to any regular blood test. If your B12 is low your doctor can give you a B12 shot. You can also take B12 supplements or try to eat more foods that have B12 (meats and fortified cereals).
