I recommend to just get in there and do those things that you are scared of. The more you do something the more you will be comfortable. Sometimes you just have to force yourself, but then after it's over you feel really good about yourself and you actually feel motivated. I graduated with an associates as well; and your first year of school you're not going to know what you want to do yet. The second year is a lot better and you start to kind of figuere it out. I did my preceptorship (capstone some may call it) in the ER in my last semester of school and it really prepared me for now. I used to be scared of talking to Doctors and giving report to other nurses. I would be intimidated, but after I did my stent in the ER that fear went away. I think after you come across that one bitter nurse who just likes to be mean to new nurses or students and just makes things difficult for you that intimidation goes away because I went through it and I've realized that I really don't need to care how that bitter nurse treats me over the phone when I'm giving report; it's not my fault that she hates her job, and I just pay no attention to it.
Things aren't as bad and scary as they seem. I still don't know what type of nursing I want to do. Right now I work in an intermediate care unit, but I was thinking eventually of getting into cardiac ICU or ER. I also recommend try doing you're preceptorship in the ER even if you don't think you will want to be an ER nurse. You get to do so much clinical stuff in there and you poke everyone who walks in that door with an IV

HA! That's my advice, it worked for me. Good luck. Oh ya, NCLEX isn't as hard as everyone makes it out to be!
