Help choosing specialty

I posted this in general nursing, but stumbled on this forum and feel the topic may fit best here.

I'm nearing the end of my nursing program and need to submit a "dream sheet" (specialties/hospitals where I would like to intern- hopefully leading to a first position).

A little about me:

I have a speech impediment and am not always fluent. When having a conversation with my peers I'm fluent 75-100 percent of the time, but if I'm nervous or having a bad day it can drop down to 40-50 percent. I already know my first few months working is going to be really difficult, but I used to be a waitress so I know I will get through it (too stubborn to quit). I've been in speech therapy for the better part 27 years- I've found the best therapy for me is work.

I'm having trouble deciding where I want to specialize due to my speech impediment. I don't want to disappoint any of the staff who will be working with me or put a patient in harms way. I feel like I've been describing a lot of my negative attributes :) Positives: I have a B.S. in Psychology.I've been told I'm always positive and likeable (and work hard to be that way- nothing worse than having a speech impediment AND a bad personality). I work hard and am a team player. It also takes a lot to upset me- no thin skin here.

If I were to describe my dream job: Midnights, overtime available once I learned the job, not a lot of time spent on the phone (I know there's no avoiding it). I've enjoyed labor and delivery, oncology, OR, heart hospital, pretty much everything with the exclusion of med surg (I enjoyed a lot of the skills I learned in med surg clinical, but it wasn't for me).

Are there any nursing specialties that aren't very well known? Any specialties where I may thrive? Any where my B.S. degree would be useful? Ultimately, I'd like to go back to school for a masters- but one thing at a time.

Thank you ahead of time.
