Refresher course starts tomorrow

I'm in California, not Texas, but I started a refresher course 3 weeks ago. Background: I worked 10 years as an RN, then out for 15 years. Let my license expire, and retook boards in June and passed, which boosted my confidence. I've felt really pretty confident until today.....

my first clinical day. Overwhelming! to say the least. So much to absorb. Where the supplies are located, how they chart....pharmacology!!!! (lots of IV push meds)...the IV pumps and other equipment. I shook just doing accuchecks and was so clumsy that I was embarrassed. (I can NEVER do anything when I'm being watched.) And I only worked an 8-hr shift...next weekend, it's 12-hr shifts. Holy smokes! I'm terrified to start an IV and I used to be very good at that...the new equip just doesn't 'feel' the same.

But still, somehow, I know I can do this. Three steps forward, one step back....but I'm still moving forward.

By the way....the other nurses in the program did not seem as intimidated as I did, so don't let me scare you. Has anyone else in a refresher program felt the same?
