Thinking of reentering the classroom

I have been teaching in various positions for 11 years. 4 overseas, 6 in university, 1 in a high-needs charter school.

I really loved the kids but the callouses of my instructional coach and the demands of the job had me burn out in addition to personal reasons. I felt I was always working and couldnt handle my own stuff.

I now have a cushy office gig but need to work a part-time gig aswell to survive. I'm thinking of going back into teaching because I need to relocate eventually to be with my partner and I'm not competitive enough to find a job in my field. Also my new field is probably dying due to AI.

I am up for a SEL middle school job at a school whose mission I admire where my partner lives. I'd need to commute an hour there and back till we can move in together (maybe 4 months).

I miss the kids, I miss teaching, but im nervous I'll burn out again and this position also won't pay me enough to survive on it alone. Advice on what to do and also how to avoid burnout/only work contract hours?
