Sorry you had such a crappy night Treehouse. I get this often too, either too much caffeine or stress. When I wake up in the middle of the night with nightmares, I know it's stress.

I know that anxiety too- it's like the fear of blurting things out because all those thougths didn't quite get a chance to settle down during the night.

I hope you get to go anyway and have a nice relaxing session (and maybe a nap!) I have always wanted to a have a session that was just nap time.
