G'day Chery
Unfortunately fatigue becomes part of life - we all get it and we all manage it. Studies have been done showing that fatigue can go on for years. Real fatigue not just tiredness. Hitting the brick wall type fatigue. You need to learn to pace yourself. Busy day followed by an easy day. When you hit the wall, or as a friend of mine put it - head in fog, feet in treacle - you need to find somewhere to have some time out.
It has been nearly ten years since my last really heavy radiotherapy but IU still hit the wall every now and then.
So what you are experiencing is normal.
