I've completed my 5th session of immunotherapy for metastised bowel cancer and coped really well with the first 4 not to much fatigue or aches just nausea but now I'm exhausted and so full of aches I find my walks have turned into struggles , tasks are difficult to complete, my concentration has gone and I'm so tired all I want to do is sleep while my body is one big ache . I must be doing something wrong I've prided myself on being strong, on dealing with my situation as it happens with a laugh and a joke , now Im a sorry sack of weepiness . Please give me some advice on how I can get my energy back , I don't want to appear a weakling when the team are working so hard to help me
