ahhhhh so damn confused!!!!!

Hi everyone! i just registered to the site. Well basically ive been trying different areas in college. Just to see what i like. Im in accounting and i HATE it.so boring. Ive always been attracted to the medical field since i was young ( btw im a male =] ), but i never decided to go into anything medical because i just didnt have the grades in HS =[. Now for a couple of months i have really been thinking about becoming a RN. I really want to work in the ER or something like that ( i LOVE hospitals lol, i was so excited when i broke my ankle last year haha). But would i require a BSN? to work in the ER? Im 19 years old and im at a community college here in maryland. There is a program to get an associates, but i dont think thats enough to get into the ER is it? so i was thinking of getting my pre reqs ( most of which i already have done. Ok now for the part im confused about. ( sorry for the long post guys!) Do i NEED to get an associates to get the BSN? like get the ADN and then go back to a nursing school for a BSN. or can i transfer straight from the comm.college into a nursing school and into the BSN?
