I am really sorry, LadyS. I have these kinds of rapid mood shifts all the time lately. I have no idea what it is or why. I am of no use to you--sorry. But I just wanted you to know someone here empathizes and cares. I hope you feel better soon.

The most effective tool for me is some kind of nap or sleep. But I can't sleep anymore, so I just have to suck it up. Sending you support and hugs.
