It's a frustrating thing to do, but it needs doing. If I keep plugging on regardless I risk a complete crash - worse, relapse - which could seriously restrict me for months. I am not willing to let that happen, so now, while in the dangerzone, I am starting to make strategic withdrawals. I have to surrender the battle in order not to lose the war.
Oddly I think it's a good thing I've signed up for NaNoWriMo - I can curl up and do that casually and gently, without feeling miserable. Withdrawing can be very isolating, so a focus inside these four walls is helpful. I can write horizontal, if I have to, sprawled out with notepad or netbook. It will take my mind off all the things I cannot do. I'm just praying my headaches are not too troublesome, because between them and the fatigue, that can cause problems in doing anything, which is horribly depressing.
Of course it would be the lead up to Christmas - but that can't be helped. If I start taking things easier sooner rather than later, I should be able to manage at least attending things, if not participating in a way I would like.
Such is life with CFS/ME.
