I understand completely where you are coming from. Before my first semester of nursing school
I was a wreck. I'd heard so many horror stories about how hard it was and how many people weren't able to get through it and I was constantly thinking negative.
Once I got in the classes I wasn't doing to well at first but I was determined to get through because nursing is my DREAM!! I met with my teachers and formed study groups with my classmates and my grades started improving dramatically. I actually did really well for my first semester!!
I'm currently in my second semester and it's hard since I'm taking 17 hours during the summer .... yea I know INSANE!!
I'm managing though and I'm looking forward to graduating in MAY 2012!!!
With all that being said ... You will do just fine! I think it's natural for everyone to be nervous going in, but just take a few deep breaths and believe in yourself. If this is what you truly want to do then you will get it and it will become a passion of yours! It's not easy by any means but very doable you just have to focus and study A LOT! Get help when you need it and form study groups and you should be fine. Good luck future nurse!!!
