Susan, yes, I've asked myself those same questions. I am right now, some of them.
I need desperately just to "BE" somewhere as well. Even thinking about going to a hotel room for a night to clear the noise out of my head from those around me. I understand.
Maybe we just need to sit somewhere and just talk...just be heard and know someone's listening without judgments or should's.
Like you, I know myself. I know my capablities, but also what I can't manage doing. So, while be aware of what I can and can't do, sometimes I just need to talk about how much that in itself sucks.
