I work in Houston, TX and have a question about what constitutes a hostile work environment.

For the past 16 months that I have been working for the company I am at, I have had to share an office with an absolutely gruesome woman. I am a non-smoker, and tend to believe I have relatively good hygiene, in that I shower daily and keep in good shape. The woman I share an office with is a smoker, has really bad health, smells of cats and smoke, snores because she falls asleep at her desk from being up gaming all night, and the worst part is that she burps ALL DAY LONG!. I can't really describe in words how utterly disgusting it is to listen to. Since two weeks after I started working here, I have complained about it, and was basically told there was nothing that could be done because of lack of space (I'm one of only three offices that has more than one person in it).

At first, this was an annoyance, and I was basically blown off. Told to deal with it, and given a fan to put in the office to cover the sounds. I was also given a set of headphones so I can listen to music. Well neither of these are solutions being that I don't like air blowing on me in an already air-conditioned office, and I don't like listening to music, because I support people and they need to have my attention. Plus, they are both just incredibly distracting. Now, this has gotten to the point that I am having physical effects. Over the summer last year I began getting anxiety attacks. I brought it up again with our HR department and my manager. I was told that as soon as the summer interns left that I would be able to be moved into an office with someone else. I took a deep breath and dealt with it up for a few more weeks. Summer ended, kids went back to school, and still no office move. Again told there was no place to move me. But in that same time, right across the hall from me, an office was built for someone else who shared an office. I asked to be moved where she once was but was told no, because that person was not in my department, yet the girl that was moved from that office was not in the same department as the guy she shared the office with either. I have tried to be patient again, but it as been 6 months. I've complained and nothing gets done. Now the anxiety attacks are back again and it's have a real strain on my quality of life.

I really need to know what course of action I can take. I feel like I am at the breaking point and have no clue where to turn.
