DON'T BE SCARED to follow your dream. I had 0, that's right 0! medical background before starting nursing school. The only thing medically related i did was take the CPR-HCP (mandatory) course a couple of months before school started.Like you I was interested in finding out about the human body, liked helping people and constantly needed new info to chew on... I spent a lot of time googling things, and watching the medical shows (no that they portray anything adequately, but still, it was "medical" and i wanted to be exposed to it! lol) and like you I was in office jobs, customer service, clerk, administrative assistant, cashier (christmas season), etc, etc... (I took a 1 year admin assist program at a community college, then had my stints as the above). But by age 23 I realized that I wanted to do something greater, something meaningful... and because I liked to help people I decided on nursing (althouh my mom kept saying I should go into social work, but that would mean mostly desk jobs again, and I wanted something different, and no office clothes, lol) so I still went for nursing. I took a "pre-health" program at a com.college (which was ok, but it was mostly A&P, chem, phys, math, and english, and some elctives) Now looking back on it I realize that only the elctive and the A&P were useful in the nursing program, and a tiny bit of chem too, but other than that it's not like I learned anything "medical ' in that program. I'm finishing up the 2nd semester of a Practical nursing program and planning to go on the BSN after... and although I "wasted" a little time on my office stints I don't I think it's okay because my organization skill, pro activness and abilit to deal with paperwork... is actually really helpfull :) So I say go for it, and they'll teach all things nursing, and it won't matter that you don't have a "medical" background, or if you want take a CNA or PSW course, so you'll have the asic stuff downa and out of the way (better than a pre-health program, I should have taken an aid course, it would be more usefull!). Good luck!
