Medsurg Burnout approaching 2 yrs, completely unsure where to go. Tips please!

This summer makes me 2 yrs into my first RN job, on a heavy MS unit on nights. My facility has a good union but our supervisors are bozos who take advantage of us finally being staffed well & float a nurse nearly every shift when we can very much utilize them when we often get admissions around the clock in the midst of heavy groups. I’m quite fed up and need a change, but I’m honestly clueless. I picked MS in order to get a grasp of general nursing skills & I’ve picked up a few things, but now the question is where should I specialize in? I’m honestly quite over bedside, which is terrible considering I’m only 2 yrs in. Being charge nurse on such a unit did not help at all.

Since we’re on the move nearly the whole night on my unit, I now quite literally want to be almost always bored at work with similar pay, but if I pick something like Psych I’m locking myself away from progressing later on, right? I’ve heard plenty of times that going into psych won’t lead to any further nursing skill growth, even though I’m a bit indifferent to more nursing at this point. I have hefty student loans to pay, so my feasible options of maintaining my current income whilst having an easier load feels quite limited. And I’m being told from a few that I should pursue NP school, but more responsibility is not what I need. I’m afraid of leaving where I’m at & frequently bouncing around different units disliking everything. How can I determine what to try when I don’t know what to expect? Should I double team Psych & more school despite loans?

What about O.R or ambulatory? I have an interview at a vein center coming up, which seems to be along those lines, but it’s per diem. Is that too infrequent of a schedule to acclimate to that type of setting? I wouldn’t say I’m the smartest nurse, I think I’m just resourceful and I pay attention to detail. Any words from anyone please, I just need ideas.
