I don’t believe in being stuck but I understand being very tired. Being very tired sometimes feels like you are stuck. And sometimes it seems like no matter how much rest you get it’s not enough. There seems to be no way to build up strength.
One thing that helps me when I feel this way is to notice the slight differences from one day to the next. When everything looks and feels the same because the routine is draining I think of the present day compared to yesterday and note the differences. Change can build momentum and sometimes you can kick start yourself.
