Am I crazy?

I am going back to a medical surgical unit after being out of a hospital environment since 2015. Worked a lot in assisted living since then. So completely bored. It is the hospital I worked at before. I am really excited even in this day of Covid. I took care of many sick and dying patients of Covid in the assisted living so this is not my first go round with that. I will be getting a 12-week orientation which is more training than I got as a new grad. I am probably crazy to go back to the hospital, but I love to learn new things and to actually take care of people rather than just feel like I am basically babysitting. Though I do love my senior friends. Has anyone done this? Gone back to med surge after a long break?
