Is it normal to keep thinking about the job you hate so much?

I work at Modells and I hate my manager. At first it used to bother me that she would talk to other workers at my job and not me but now it doesn't because I see her for the bitch she is. She only has a few words to say to me and I don't like her because she doesn't express a genuine interest in my work performance. Also she walks around with a scowl on her face and I hate being around her. All kinds of nasty words come to mind when I think of her. The hate I have for her is so intense that I hope her car breaks down on the highway.

Also I feel that some of my coworkers single me out and talk amongst themselves. I have developed hatred for them too. I used to make an effort to reach out but I stopped because I don't get the same reciprocity from them in initiating conversation. I am miserable some days. However on other days I can be in a jovial mood, particularly when the manager I hate is not there. Also sometimes when I am working I start to frown because thoughts invade my mind about how I feel singled out and the disappointment of having a manager who I dislike. Is this normal?
