Big dream, little problem...

Yes, I am yet another one that is considering nursing. I am 23, married for 6 years, and we have an almost 2 year old daughter, Amethyst. I never even thought about it until I had Amethyst. The nurse that I had was AMAZING!! She made me feel soooo great, and I would love to do that for other people. I would only want to work in the NICU, L&D, mother/baby, nursery, anything that has to do with babies and moms.
I have about 30 or so college credits. The nearest school is a really small community college that doesn't offer much of anything, especially not nursing. Most of my credits are in art. I have actually started the prerequisites twice, but they are such a pain in the butt!! Not that I don't like them. I love learning. I just do much better on the hands on stuff. I have an impossible time sitting in a classroom for 4 1/2 hours talking about math.... or english. I have thought about clepping these. I would like to clep all of the prereq's actually. I already have medical terminology and psychology.
Okay, here's the problem... I am terrified of people vomiting. Well, I am actually getting over it, since Amethyst came along. I can handle anything else, but that one really gets me. I don't get sick, just scared. I know I should probably just find something else to do. In fact by the time I go to bed at night I have convinced myself I couldn't handle it, but the first thing on my mind the next morning is nursing. EVERY DAY!!! I don't know if I should just swallow my fears and do it, or keep pushing it out of my mind. And if I do it, where should I go? My husband is army reserve, and he is gone right now, so I am considering everything. We live in NM, but I would be willing to go almost anywhere that I could get in and get started.
I just feel like, if i don't try I will regret it for the rest of my life. I don't know if this is even understandable. I just needed to get it off my chest. I can't talk to my family about it, because they don't think I can't do it.
Okay, any advice??? Thanks a bunch!
