I'm looking for a bit of advice and maybe a bit of 'yes, that happened to me and I was fine'.
I had a nasty bug last Wed/Thu. Lots of stomach cramps and dramatic wailing and crying (from me, a grown up, apparently). I couldn't eat on Thursday or Friday. I took things gently over the weekend. Went back to work today and felt like a ghost - feel very insubstantial.
I worked out that I'm not getting more than about 800 calories a day. If I eat, then the stomach cramps start to come back. If I don't eat, I don't have any energy. What should I be doing to feel better?
