Having to rest today. Had done a lot of walking yesterday (aerobic pace). With CFS* (aka ME** and SEID***), there's an "exertional intolerance" and it takes extra time to recover from the exertion involved.
Fibromyalgia is also acting up big time, for the first time in a long time.
(I deal with several additional conditions, mostly autoimmune in nature.)
I try to accept it and pace myself. It can be challenging and disappointing.
I feel unusually "fragile" and am trying to distract myself from very depressed thoughts. I just feel like it's all an uphill battle (too often).
Tomorrow is another day, thankfully.
