I have to agree with healingme4me, it isn't worth running away. I did that a lot when I was younger. I have been at my current job for 17 years now, but I tell you...things have been so rough lately that it's hard not to run away. I'm trying hard to focus on the positive things in life in general as well as the positive things at work. I wish I could say it's easy. It really isn't. I fail all the time. But I keep trying. If your co-worker is really that bad, I hope that life will work it out that she'll move on from your work place. It sucks that people are like that, unfortunately, life has taught me they are everywhere.
