My DM finished ten days of radiotherapy last week on her lung and brain. She lives 300 miles away and I have a FT job and two kids so can only check up on her by phone. She has a good support network around her and they're visiting, bringing food etc... but she's still very very fatigued. I keep telling her that it's normal (it is) and it's part of getting better, rather than the cancer making her feel ill. Does anyone have any experience in how long it might take for her to feel vaguely normal again?
