Returning nurse

If you're willing to relocate to an area with a nursing shortage, I imagine you could find a job in any number of nursing fields right now, including ER.  So many places are desperate for staffing. Three years isn't a terribly long break, and two years of med surg experience should certainly put you at an advantage over new graduates who were stuck doing clinicals in sim labs because of covid.  You'll be surprised by your muscle memory when it comes to clinical skills. I'd review lab values, common meds for the type of unit you're hired into, and request a longer orientation than "experienced" nurses usually get since you've been out of the game. Good luck!
