I had to make a decision between teaching and Speech and Language Therapy. I chose the latter because I realised that teaching would be a better pod but less satisfying version of what I already did (I was/still am a tutor). I did some cover supervision work and it was one of the worst hours of my life with one classroom (although the upside was I did get to throw half the class in detention). Teaching is mostly management with a bit of education thrown in and that's not what I wanted to do. I love teaching but I like to know I'm actually getting the job done. Plus the amount of hours I'd have to spend planning just to satisfy the requirements of a lesson just sucked the joy out of it.*
SLT (which you might want to consider as a languages graduate) was a way for me to use my skills in a way that I found meaningful and enjoyable. Teaching, for me, felt like however good I was as a tutor and an academic (and my results with students spoke for themselves there) would get lost in the mire of management, which I know I'm not so good at.*
It sounds like you're looking for a way to use your language skills and it seems like you might be thinking that teaching would give you the most opportunity to do that over nursing. Once again, though, I would direct you towards speech and language therapy if that's the case. Plenty of opportunity for you to use your skills there.
But even in nursing there are opportunities for you to use your language skills. You just have to look for them.*
Don't do teaching just because it's obvious. If I'd done that, I'd be miserable right now. There's a reason I avoided it for so long and I'm glad I did. *
