<human>: Provide a brief overview of the text.

Hi, all. I'm a 20F working as a diet technician at a hospital. I do this full time as I go to nursing school. I'm not in my clinicals yet, that's next year. I pay for college myself but I live in an affluent area.

There's a few girls at my work, all ranging from 19-23, who basically hate me. They also work in the nutrition department but are relatively new. They've been telling other co-workers how they don't like me and think how I'm stuck up and privileged. 

I get along great with the docs, nurses, my bosses, basically everyone else but these girls. I caught one of them telling a nurse how she doesn't like me because of how I act and how I think I'm better than everyone else and I'm a know-it-all. One of the girls was in the nursing program but dropped out because of her grades (I think). 

I used to model in my teens and I'm really into nutrition and eating right, and it shows in my body. I get a LOT of attention from guys and I'm always nice and talk to them, but I feel like they think I'm flirting with them. I've been nice to them and I don't gossip about other people behind their back. I always say hi and good morning/afternoon and do my job.

I know I'm quiet and reserved but I'm here to do my job and make people's hospital stay a little better with decent food. I don't get WHY i'm hated by these girls, and it's making me really want to quit. I have great hours and a great assignment, so I feel like these girls really want me to quit so they can get my spot.

What am I doing wrong? What can I do for them to leave me alone?
<bot>: I'm 20F, and these girls at my work totally hate me. I don't understand what I'm doing wrong. I'm quiet and reserved so maybe they're picking on me because they think I'm weak. Help!
