Thank you so much! I hope it works. It was a relief to find out that the problem isn't to rest when I'm tired, but what to do after the rest (to help myself not to become prisoner of my own thoughts). Some days what to do after the rest can just be to use Netflix (let go of my many thoughts and focus on something else)the rest of the day, while it may be a walk, do housework or whatever another day.

All in all it seems to indicate that (self-) acceptance is the best way to live always, but especially in the winter time when the energy level is lower than usual!
