I need help! What should I do?

I need someone to help me organize my thoughts...

I have worked in Adult ICU for four years. I stayed at my last job for three years and I really liked it, for the most part. It was in a community hospital on the outskirts of the city. The people there were friendly and I did well there.

I left a couple of months ago when the staffing ratios were becoming an issue. I went to a large teaching hospital ICU and got a considerable raise. The problem is that I just don't feel like I belong in an environment like that. I have been having problems with anxiety (which I never had before in my entire life), lost 10 lbs in month, and started having heart palpitations. With the support of my family I put my notice in recently. I don't know what I'm going to do next.

I am wondering if I am supposed to do something entirely different. I am breastfeeding my baby and I would like to spend as much time home as possible, but if not, at least have enough time during work hours to pump. I have an interest in lactation consulting and am active in the La Leche League. I applied to midwifery school but won't find out for 3 more weeks. I don't know what to do...

Can someone offer suggestions? They would be much appreciated.
