Sleep Schedule and a Few Irritating Things

I work.  It's three days a week or 6 days a pay period.  I wake up at 530 to get ready and work from 645am to 700pm.  I don't mind it.  I love my job.  But it sucks to still wake up that early on my days off!  Syd sleeps in til 830 some days and at least 930 on other days.  I couldn't ask for a more considerate child, but I can't manage to get my internal clock to cooperate.  Oh well, such is life.  Maybe I should get important things taken care of on those kind of mornings.
Speaking of work.  I work my butt off.  I'm an emergency room nurse.  I like to hustle.  I don't like orders to be waiting and I don't put off my patient care.  I move pretty quickly and help my fellow colleagues.  When I first started working there 11 months ago.  I was bright and peppy simply from being relieved my license had changed from Arkansas to Georgia without much hassle, and I found a job in such a quick amount of time after moving.  The environment was/is better most days and the pay is better.  I still love my job and I'm still peppy and sweet with most people.  There are a choice few who are lazy to the bone and do no return the favor EVER when I help them with their work.  When they should be working, they're talking on their cell phones or eating in the break room.  Which is fine... whatever, do whatever floats your boat.  But it really lowers my opinion on the type of nurse they are and also makes me not want to be very chipper with them.
The problem with this is my work does peer reviews.  One of these said lazy people has gotten my review to do.  A comment was made to another nurse where one of my friends could hear it.  It was "I got Ashley for the peer review, but her attitude has changed a lot lately towards me."  Two problems with this, 1) Reviews are supposed to be confidential which obviously mine is not. 2) My attitude towards them has definitely not affected my work performance.  The fact is, I'm not rude to them and I still communicate with them and help them.  My interaction with them is merely on a professional level.  I don't chit chat with them while I'm supposed to be working.  But because I'm not as "peppy" toward them as I might have been previously, my peer review is probably going to suck.
Now that I've vented, I'm not really all that worried because I'm sure my work performance will speak for itself.
