Yes, I think we all go through those episodes. But you've definitely come to the right place to find support.
Keep yourself occupied as much as possible while you feel this way - do a puzzle, scrapbooking, crosswords, take a walk in the park... anything to engage your mind, emotions and brain.
I know it may seem the easiest way out, but sitting at home on your own really is not healthy if you are in this frame of mind.

I hope you feel better soon (((HUGS)))
