Girl, I am completely in the same boat!! I have also worked in group homes, I remember when I first started I was really nervous and it felt overwhelming, but I ended up managing two of the homes before I moved, I never would have thought I would get to that point on my first day of work! There is always a learning curve with anything.
As far as not feeling prepared, I think that is the standard feeling for most fields when you first get out of school. I remember expressing this to my dad when I got out of school the first time (he was a doctor), and him alleviating my fears a bit by saying that nobody really does, and he too didn't feel prepared when he got out of school (This was crazy to me because all I could see was he had always been a wealth of knowledge and a great doctor that everyone loved, but I neglected to realize that he had been in practice 40 years, it didn't happen overnight!)
That all being said...I am still most definitely terrified!
I also just want to get to the point where I feel I am competent and I don't feel like I am scrambling to keep my head above water, but I guess that will come in time. It is scary to start something new and start at the bottom and have to learn everything...it is especially scary to realize the responsibility and the scary patient loads that people talk about on here. And when you hear that it takes years to actually be pretty good...that is kind of daunting! I think it has been a little more real and scary for me since I was accepted into a nursing program. Don't get me wrong, I am SOOO excited, but still it is scary for me.
I am a little afraid of the mean nurses I have heard of too, the yelling doctors, etc. Hopefully I don't cry!! I have a tendency to do that when someone yells at me and I hate that! (and here I am thinking of coming into the army as a nurse eventually...ha, I have to get thicker skin I think!) Hopefully I will get over that.
Anyway, just wanted to let you know that I am terrified as well, and I can really relate to your fears. I am so excited about getting into nursing, and most things I know I can handle, but there are some mental and emotional things that I am nervous about at this point!
Good luck Lisa, hopefully we both get over our little issues!
