Dont dooo ittt!!! No sugar! Maybe youre in a bad mood b/c you are seriously craving some sugar?
I think I understand what you are saying about your job though. I have several nurse friends and they are mostly neutral about their jobs. So... eh. Itll get better. Just keep doing what youre doing and take small steps!
Good luck and keep us in the loop... even if its to vent. Because we all need that sometimes!
