hi. My teen has had a cfs diagnosis for just over a year now after three previous years of illness. He seems to have hit a wall and is giving up on all advice for sleep patterns, nutrition and pacing. It is a constant battle between us now. He is almost 16. I just want to do the best for him and expect he is trying to exert control over his very challenging life, Any tips on how to help him?.He is under a specialist hospital, but there isn't support for parents as such. He is in school part time and is due to sit gcses next month
