Are you in a 2 year ADN nursing program? That is what I did (after being a paramedic for awhile) and then later got my baccalaureate.
It will be easier to find a job as a new grad RN than as a teacher I believe and where I live nurses are paid better than teachers. But it is more important to do something that you will be happy doing.
When I was in nursing school I thought that microbiology would be the death of me. I hated that class and began to doubt my nursing major.
One of the great things that I like about nursing is there are so many varied opportunities. I like critical care nursing and cardiac. My sister works on an orthopedic floor. You could do peds if you like the wee ones. Or you can work in a doctor's office, work in public health or be a school nurse. You can make big bucks being a travelling nurse. So many options.
Good luck in whatever career you choose
