I have a similar story. Have worked in private duty respiratory care, nursing home, hospital, community health, dialysis and corrections. Driving anywhere from 30 mins to 1.5 hours, in the snow more than half of the year, after working 12 hour nights. I have awoken more than once by hitting the gravel ditch on the wrong side of the road. Leaving jobs for ones that were closer to home, daytime, and realistic hours worked. Am happiest in my current position. I too wanted a baby, but it did not happen, my husband did not want to adopt or foster. Being childless is the club I never wanted to join. People have told me I am selfish, too concentrated on my career, why didn’t u do IVF, etc. judging me about my non- choice about having kids. People bond through their kids. Talking about them, how old, what grade, the nephew math, etc. It is lonely to be in this club, childless. Felt homeless as a nurse too, jobs to get by on, until something better came along, (5.5 years one time) hoping for improvement.
