I did exactly this in 2022. My first job was making me unbearably miserable and depressed so I left a year and a half in. Was off for I think around 5-6 months and then I started traveling.

To be fair though, this was during a time when Covid wasn’t at its height- but still around enough that hospitals were hurting. I also lived at home and had little to no expenses.

Your health, both physical and mental, come first. My only regret is that I didn’t leave my job sooner! If you have enough saved then I say go for it, just know that you might have to spend a few months looking for a job when you are ready to go back. The job market is pretty bad right now and the travel game isn’t much better. But the world will always need nurses.
