Living with ME/CFS is... Being total loss the rest of the day after an hour of mild activity.
After a (not very intensive) conversation of half an hour in the morning and a travel time of 2x 20 minutes (cycling at ease), I can be so exhausted that I am not able to do anything else for the rest of the day.
And "nothing" is really NOTHING! So, not watering any plants or do a quick dishwashing. I mean I spend the rest of my day lying in bed like a zombie, watching predictable TV series. I would rather read a book, but that is not an option. Even short, simple texts require a concentration that I can't affordin this "zombie modus". That would cost more energy than I have left.
When it finally is evening, I hope there is a leftover from the previous day that I can warm up. Because on these days I don't manage to cook. No more energy available. That was completely used already in the morning.
Meanwhile, I am reasonably used to a life with ME/CFS. So, often I cook for 2 or more days at the same time. With a little bit of planning I manage to eat healthy every night. Unless I have too many of this kind of days in a row, of course...
