I am in the same boat! I have been working as a nurse since 2013 in home care and for the developmentally disabled. I just started at a nursing home on the sub acute unit and my first shift alone I could barely get through the med passes and became physically sick. I pushed through it and and I am now going into my second shift (I work there pier diem). It seems that many nurses have a hard time for at least the first year and working in a new facility is stressful on anyone. Hang in there it appears we are all in the same boat- I wish you the best of luck!
