I think it becomes a problem if you worry and focus on it.
I was exhausted for almost a year, needing to rest ever afternoon. Then I realized it was the same time every afternoon. Hmmm.
Now, I was not very functional at this point and I realized I needed to a) try and move more b) re-find my interests so that I could attempt to redirect my mind, and c) for my very busy worried mind, rest it with meditation. It may only rest for 3-4 minutes right now in a 1 hr meditation but that’s an improvement.
A whirling, busy mind and a body in pain can release chemicals we don’t need in the moment
