Welcome to the site, tina! Glad to have you with us. Also glad that you are fairly sure you wanna be a nurse.
I know there have been many posts out there about 'nurses eatting their young', etc. I should point out that nursing can be a bit stressful. Working weekends or holidays isn't for everyone, but illness knows no holidays. Combine that with the acuity of residents/patients.....plus the unique personalities of each and every nurse out there.....well, it happens. Heck, it happens with other professions, too; why nurses get singled out, I have no idea. If you keep that in mind, I am sure you will be fine.
