I know someone asked about my experience at Barts and my memory is not great, so bear with me.
When I was seeing the consultant and nutritionist there after the group thing, they asked me to get involved with a diet (not for weight loss) trial ~ which I did try. It could have been a sugar free one or a wheat free one; I got the wheat free, but it was more involved than just cutting out wheat products, I had to cut out things like mushrooms, sugar, alcohol (I don't drink much anyway) and some other stuff which I can't recall. I don't think I lasted more that a couple of weeks tbh as it was really hard to follow, but I didn't feel any better over that time.
During my group sessions, we were taught how to manage the illness, how to be kind to ourselves, how to get support. I was the only person in the group that worked full time and was a lone parent; nobody could understand why I couldn't 'just go part time' but it isn't possible for everyone to do so. The biggest triumph for them as regards me, was when I said that I had started to sometimes use instant mash! they were ecstatic! I am not a quitter and it took me such a long time and a lot of effort to slow myself down...I did manage to, but I still feel ill with it.
I think I should have listened to the advice I was given at the beginning and rested. It took me about 6 years before I could let myself stop living in the past. I used to say 'I used to be able to...' fill in the blanks with any number of activities I did and all at 100 miles an hour.
The guilt is normal, because we aren't used to giving half measures of anything are we? and asking for a little slack or some help is alien isn't it? but unless we do make these adjustments, I don't think we will get well.
Having had Dd I was able to take a years mat leave and then tag on 5 years of career break which has been great, but has not made me better, it's just meant that I've been able to be less physical...the stress though has been dreadful; never knowing if I can make all the bills or keep the car running etc.
As a last for now, I went on a weight loss diet around 10 years ago for my own benefit, nothing to do with ME. It was a detox type diet and very strict. I had to cut out all dairy, all bread, rice, oats, and anything containing those things, so no pasta, sauces etc. Lots of other things cut out too, no sugars for instance, no alcohol, no fizzy, no root veg (high in sugars) and no caffeine. So whilst I was losing weight, it did not make me feel any better as regards the ME. The only thing I continue to not have is caffeine; no particular reason, but I do.
