I am trying to decide how many hours I can manage at my job as a Part time Librarian without making my CFS worse and continually crashing. My employer wants me to notify them how many hours per day and per week I can do. Perviously I had been working 2-3 three hour shifts/week and 1 six hr shift every other week. I was managing ok on this but had a severe relapse in Sept that lasted 3 mths long. Since then I only managed the 3hr shifts twice/week and did my first 6 hrs one this weekend and really crashed hard. (bedbound 2 days) I need to earn money and for the most part find the job helpful - I can get out of the house, feel useful etc. My fear is that I may be over doing it and thus causing these crashes/relapses. My doctor don't let fear decide and try to manage the new schedule of 18hrs a week. After this last crash from the 6 hrs I don't feel I can do that. Now I have to go BACK to my employer and tell them I can't manage the 18 - but what should I anticipate as to what I can manage now? I think I'm at the end of the rope as far as negotiating my hours so don't want to run them around either. Luckily I have a good union so that is why I am able to do this at all. Any advice is much appreciated!!!!
