Hi User,
I've had days like you are describing. Do you pray to your HP? I always start the day with one, and it is a big help to me throughout the day.
If you would've asked me maybe three months ago "does praying to your HP help you" I would've laughed in your face. But, really, it works. Call it whatever you will, meditation, pray, quiet time, give it a shot and see if it calms your mind.
Hang in there!
Karen
