Good to see all the open responses. You will not enjoy your work while feeling tired, anxious and depressed. It is too hard to look after anyone else while you are feeling so low yourself.
A suggestion: make an appointment with specialist doctor. Send an email to them prior to visiting, listing your problems and how you feel.
Take the same email into the doctor when you visit and go through point by point your concerns.
You have put a lot of work into becoming a nurse. Now is not the time to be looking for a different role within in nursing.

I would spend all my days crying - if I didn't have my antidepressants. My antidepressants make it so I can live and function.
Don't undermine your struggle. Make it very clear to the doctor that you need help.
