Jessica, is it possible you're just trying to do too much? I haven't been a member all that long, but I've noticed that you're here a lot, taking care of just about everyone as best you can. From what I've seen, it's a darn good best, but I've wondered how you keep it up!
You're such a fine presence here: you contribute so much to making Susan's what it is, and it would be a huge loss to us all if you gave up the work you do. That said, I get that moderating a forum can take a lot out of a person; especially a forum like this, that runs with such a high level of emotional intensity.
So... cut yourself some slack, OK, Sis? You're a wonderful, kind, caring person, and you don't have to be Superwoman to prove it.
Take a sabbatical if you need to, find ways to take care of your own needs as well as everyone else's, but don't for heaven's sake think this is an all or nothing thing. You're good at this, and giving it up is NOT the only option!
