Dill Pickle

I am needing to rant and am also looking for advice. I have generalized anxiety disorder and depression. I do see a therapist and counselor. I left my job of 6 years taking care of someone in their home because I started worrying about my future career (that patient went in and out of the hospital a lot which left me without work while they were in the hospital). I've only been at this new job for 2 days but my stomach is all tied in knots about going back. My previous employer does want me back and is trying to offer me more money to come back. I feel stuck and at a loss as to what to do. This new job is night shift so I've had to adjust my sleeping patterns and is messing me up mentally and physically. I've started having issues with sleep deprivation, night (or day sweats) while sleeping, diarrhea, panic attacks, and just feeling generally unwell. Lots of crying, etc. I feel like I'm gojng crazy. They don't have any day shifts at this new job so I fear I'd be stuck doing nights for a while. I have thought about getting out of nursing altogether but I honestly can't afford to right now. The thought of going into this new job tonight makes me feel like I'm going to vomit honestly. The lack of sleep I got during the day has not helped. I feel physically and mentally unwell. When the job I left called me I started feeling my anxiety symptoms lessen a bit. I know this sounds horrible but I just feel like calling out sick with this new job and never returning. This is not like me as I rarely call out sick and I always work overtime etc. I don't know what to do.
