After getting some sleep, I do feel a bit better today. I put on a little Oasis - "What's the Story, Morning Glory?"
and felt better, too. I wish I could control some of these plummets in my mood. I do work to maintain a positive attitude, but sometimes it all just crumbles away, and then I feel terrible.
I tried to make a deal with the Devil, once. Turns out I didn't have anything he wanted.
You will never find a more welcome hive of love and humility.
