Am I crazy to go into Nursing in this day and age?

I'm in my 30s and have decided to quit teaching to go into nursing, so it's back to school for me. I'm excited at the prospect of nursing someday and will begin my studies in 2026, but I work with nurses at the moment and I'm not exaggerating when I say that every single one - every. single. one. - is all burned out and have advised me against the profession. They've outright begged me to run for the hills and "not make the same mistake they made". Most of them came into the field with a burning passion for the job, and now they dread the next day of work, and the next, and the next. Of course there are good days, but it seems like the bad days can be *really* bad. Many have told me that they would easily pick any other profession if they could turn back time; for others, they've settled into the job because they have no other choice and are simply going through the motions. I'm trying not to be discouraged, and I wouldn't want to discourage anyone else reading this; I've seen the strikes, I know that nursing isn't all picnics and roses, and that stress comes with the job, but i didn't know it was this bad. these nurses are on survival mode.
As a former teacher, I had my own passion kicked out of me, so it's eerie how the nurses sound identical to me when I was at my rock-bottom during my teaching, and I wonder if I'm just jumping from one stressful career to another.
Are there any nursing students around that can share their experiences so far with their placements? Are you still looking forward to nursing someday despite the challenges?
