I have ME Myalgic Encephalomyelitis and finding it impossible to lose weight?

I have ME: Myalgic Encephalomyelitis and finding it impossible to lose weight which is making my condition and self esteem worse.

I am a 19 year old with ME: Myalgic Encephalomyelitis. I desperately want to lose some weight but I am struggling to get any exercise because it is far too painful. I have been in physical therapy before but because of my hypo mobility they pretty much told me exercise wont help my muscle pain and signed me off. I understand that diet is also important but I also have a eating disorder which I have had from being young so I eat really poor food and no matter how hard I try I cannot change that. There are foods like meat, potato or fish that i physically cannot eat without being sick.I only work 2 days a week because I can’t handle any more and I frequently use a wheelchair or crutches. I seem to be putting on more and more weight and I don’t know how to lose it.

When I stretch the skin under my left rib sinks in a noticeable amount and when I bend it sticks out but the other side don’t do it. When I have questioned it before I was told that everybody’s body shape is different but I feel like it’s more than that. It just don’t feel right.

I’m not obese but it feels like someone has strapped a sack of spuds to my stomach,weighing me down and giving me lots of pain. I need to loose some weight for myself physically but mentally too. I’ve missed out on a lot because of my illness and don’t want anything else getting in the way of me finally being able to enjoy my life.
