Should I quit my job or is this normal/typical?

I work for an organization that treats me like crap. I don't even know where to begin. I was hired to be a software engineer, and immediately upon staring the job, I was pot in a different group where I have done absolutely none of the work I agreed to when I was hired. I am left out of most social events. I get handed the worst jobs--and I mean crap jobs that no one else will do. I have been mocked repeatedly for not having attended Virginia Tech. I have an office mate who is pive aggressive. My boss looks at the floor when I say hello to her in the hall, and the only time she actually talks to me is when I have done something she doesn't like. Her interpersonal skills are sub-par. For the first 2 years I was here, the ual harment was unbelievable. I have had to report 3 different men for inappropriate behavior the worst being about 2.5 years ago, when one of my coworkers came into my office and propositioned me for while all of my other coworkers were at a retirement party down the hall. I had a panic attack during/after the incident, but somehow managed to get myself together just enough to report the incident to EEO, after which he was investigated and fired for having a history of this behavior. I will never be comfortable here, ever. I hate my job while I am there, but lately the hate has been coming home with me. I have been putting up with this for more than 4 years. I am a good employee, and I tend to get very good to outstanding marks on my reviews, and I struggle to stay positive. However, I am beginning to think I deserve better. Should I look for another job, or is this normal?
