New PACU nurse feeling down

I have been a nurse for the past five years. I started working in CVICU for 2 years and then took a office nurse position due to moving. I was recently laid off from work and am now back at the hospital doing PACU nursing.

I have to say that going back to the hospital (after not being in it for two years) was pretty intimidating for me. I have been giving it my all (bringing home study materials) and working as hard as I can. I got my first review back and it said that I operated like a new graduate. It also said that I tire easily, do not seem happy to be on the unit, and that I stand and watch everyone with my hands behind my back.

Needless to say, I was crushed! It did not have one positive piece of information in it and left my confidence feeling rather shattered. I recognize that this is a fast paced environment and wonder if I will ever get the hang of it. I guess perhaps I could use some encouragement and would love to hear anyone who has had a similar experience and how they have dealt with it.

I want this job to work and lord knows with this economy and having two kids it would be horrible to have to look again. Please help this very discouraged nurse!!!
