Ann, I'm so sorry. I'm afraid I would be screaming and pounding the walls. This is truly one of the most insidious disorders. Sometimes it makes me want to yell at my body: What EXACTLY is it you want from me??? and question whether my time on earth is to be spent just walking around and/or staggering from exhaustion. I'm glad you're sharing this for several reasons. I think it's good for you to put it down in words and I'm glad you're doing it in detail. There's the chance you'll discover something the rest of us could use. And also there's a chance that someone -- whose brain is clearer than yours at this point, because possibly they've had some sleep-- will be able to see something, see a pattern, and make a suggestion that might help.
I know it's not a question of giving up, you have to go on and try and try. What I hope is that you won't get depressed. I'm afraid I would already be there. You're very commited to these boards and we all appreciate it, and I want to say: Just stay close. We all care very much about you and will be hoping, hoping, that something works soon for you.
