https://www.thescottishsun.co.uk/news/1445538/singer-amanda-hendrie-me-battle/ This article, which I can't see here on the site, shows the severe and even life threatening nature of the condition. Apologies if the article is already posted - I couldn't see it. The woman featured in the article has been ill with ME for years, but the death of her mother has made her even worse and she can no longer speak or sing. She is in the 25% group severity-wise. From the article: The article is by Mary McCool, and it's definitely one of the better ones.
