Not sure if you’ve ever worked an office job or not but don’t underestimate the exhaustion you can get from sitting at a computer all day. Nursing is extremely demanding so you’re obviously no stranger to hard work and exhaustion - but maybe give the office work a go for a bit and see how you feel.
I used to scoff at the idea that a 9-5 office job could be tiring when I had a more physical job. Turns out it really can be, just in a different way.
Try things out and then see if the extra money is worth losing your weekend respite.
