Dealing with co workers

It has been a boring week around here nothing to exciting. I was a bit emotional as it was my time of the month. I always have a hard time at work during my time. I work with someone to say nicely she is very mean. I have had a lot of problems with this girl and it's not just me. Before I moved desk I had to sit by her. Now I sit by my boss which is much better. She would spray my stuff with hospital spray disinfectant which is a horrible smell I think. I noticed she would only do that when she would be mad at me. Which was most of the time. She would leave a row of files if I went down it. It got so bad that I noticed that if I sat down at my desk she would get up and leave her desk and not come back. I don't sit a lot at my desk very often but after I noticed she was doing that I would try to leave my desk and when I saw her go back to her desk I would go back to mine. Yes, that was stooping to her level but that day I couldn't take anymore and had to do something to make myself feel better about the situation. Then she would get pissed and throw her stuff around like I couldn't come and go to my desk as I please. We have a lady Stacy who started about two months ago and she has problems with the same girl. A lot of people have problems with her. Stacy has went to break and come back with her area smelling like disinfectant spray. When she took a drink of her pop it tasted like disinfectant. Her excuse was that we all smell like cigarettes. But I have been smelling like that for over five years. Last week when Stacy came back from lunch the girl was mad at her and sprayed her with disinfectant and it got in her face. We have had more people quit over this girl. My boss moved me in with her after I told her if things didn't change I was going to transfer out of the department or quit. I use to let this girl bring me down. She goes out of her way to be mean. How do people act like that keep their jobs. At times I wish I was younger and didn't have so much on the line because I just want to knock her block off. Well fortunately for her I'm past the kid games and in the real world. I find it hard to pray for her but know in my heart that God will make it better so I do. My boss is off work most of next week and the following week. I have the most trouble with her when my boss is gone. My stomach churns when I think about working that week and what it might in tale. I'm more worried about Stacy she is going through a lot in her personal live and the girl seems to have it out for her right now. I have already talked to Stacy and let her know that she has any problems to let me or our office manager know. I think our office manager needs to know about this girl anyway. Wow I wasn't expecting to go into all of that. I'm done ranting and raving.
