To be or not to be..

Okay so maybe I need a little encouragement. I got into the nursing thing thinking I would do the RN program and took Anatomy only since I was pregnant and I didn't want to take too many classes and have the baby halfway during the semester. Aced that but decided to do the LVN program first and do the ladder up to the RN program and possibly beyond if I have enough motivation. Currently, I'm taking two of the four pre-requisites I need for the LVN program and reality is starting to hit me.

I was cutting my daughter's nails the other day and accidentally cut her skin when she moved and it bled and bled and I tried not to panic. I finally managed to make it stop and bandaged it well so that she wouldn't get her cut wet with her saliva (she's only 2 and a half months now and likes to suck on her finger). She didn't cry so much but I felt sooo guilty and even with two of my other children who I'm sure I've done the same to, it hit me hard this time because I wondered what could happen if I was a nurse?! Some people make it seem so routine, being a nurse, but I sometimes forget that these are peoples lives in their hands. These are going to be peoples lives in MY hands. What if I do something wrong, what if I do something that makes them worse then when they came in? It's not like I can go back and say "oops!" and press the delete button. I am totally freaked out. And taking these pre-reqs aren't like taking pre-reqs for the RN program, these pre-reqs are almost like taking a nursing class..and they are, they are intros to nursing so it's a lot of work!

My husband and I decided we would sacrifice me working right now to get these classes done and get into the program. I have my B.A. already but I wasn't happy with what I was doing and wanted to go back to my first dream (which would have been easier to do had I done it when there was only one child, now I have three and I commend all who have managed to get through the program with children cause it is TOUGH!). Sometimes I'm not even sure I'm making the right choices if I should even do the LVN or just do the RN, sometimes when things like what happened with my baby scare me and I'm not even sure if I can handle being a nurse because I wouldn't want to mess up on my patient. Sometimes when I have all these papers to write and drug cards to do, I feel like giving up.

Help?
