Former nursing student chiming in.
Is there one you think you would enjoy the most? Does one interest you more over the other?
I feel like the best nurses who I encountered (teachers, classmates, and nurses from my clinical rotations) loved nursing to such an extent that they couldn't imagine working any other job. It is a tough job. High stress environment, hard to find work right out of school, understaffed hospitals, long hours. Nursing honestly isn't for everyone and many of my old classmates are frustrated with the work and are only motivated by paycheck/benefits.
Can you see yourself successfully performing either of those jobs with your degree of SA?
I'd like to mention that I learned the hard way that nursing wasn't for me. My grades were ok but my performance on the floor during my clinical rotations was a disaster due to SA. Talking to others, speaking up and advocating for my patient, and asking invasive questions was pretty rough for me. I also had trouble politely interacting with unruly patients or balancing manners with efficiency/timeliness. I was often behind with my nursing duties. When told to speed up, the stress/anxiety would hit hard and I'd focus on my to-do list so people would stop yelling at me. But that also meant that I completely disregarded manners and that further aggravated the nurses.
Even if I performed my tasks correctly, politely, and on time, patients would still request to have a different nursing student because I was just awkward/quiet/weird. Other nurses even noted that in my evaluations and it was pretty disheartening to hear all of that.
It's not impossible to be an awesome nurse with SA but I think it is a challenge. If that's really what you want to do with your life, then by all means go study hard and kick butt in your clinicals.
I haven't explored dental hygiene as a profession but I think i would prefer it over nursing. I only have brief conversations with my dental hygienist and we hardly talk when she is working on my teeth. I just let her focus on her job and follow instructions she occasionally provides. Then at the end, she points out what I can do maintain/improve my dental health. Sounds like a cool job to me.
Anyway, I may have went on a rant but I hope that some of this was useful. Good luck!
