An update, in case anyone is paying attention. I have less than two weeks left here at my soon-to-be-ex-place of employment. Although I still have no idea what in the world I'm going to do job-wise in the months ahead, I do feel a lot less stressed about it than I did immediately after giving notice. The initial panic has subsided and now I'm just winding down my time here and considering my options with a little more perspective. It also helps that I started grad school last week and that is really off to a great start. It feels very right to be moving in that direction (Spiritual Psychology). Many questions remain unanswered, but I feel much more trusting about how things may turn out than my brain would think I have any right to be. Which I guess is what living from the heart is all about. 
Hello!
Seems we're in similar circumstances. I was a nurse but quit my job recently. Saturday was my last day. It feels great, a little scary, but you know when it's the right thing to do. Sometimes you just have to take the plunge and have faith that the universe will take care of you....
