I just don't get it!

The people I work with are such jerks. Not all of them, but most of them. And I just don't understand why it has to be this way. I've been back at work for 2 days, and for 2 days I've come home angry and depressed. I tried to just get over it, but you know what? I dread what new crap I'm going to have to endure tomorrow, and that just makes getting over it impossible. And most of the crap stems from just one evil, hateful, two-faced woman. She's a grown up for goodness sake! Why does she have to act like a snake all day long?? I just don't get it!
I've actually made a list of all the crap I've been told by other people. This is all of the stuff she's been saying about me to my co-worker while I was on vacation:
1. I'm a terrible cook.
2. I'm a bitch.
3. I yell and scream and go-off on people.
4. All I ever do is smoke and talk to Ryan.
5. I'm jealous and hateful.
6. I'm a slut.
7. I'm a terrible employee.

See what I have to put up with? And the whole time she's talking shit about me, she's being oh so friendly and polite to my face. Grow up!!
I don't hate people. Its just not in my nature, but every time I'm standing there and she's talking to me with that fake smile on her face, I can't even hear what she's saying because in my head all I hear is my own voice saying, "Holy crap I absolutely HATE this woman!"

I tried like hell all day long to get over it. But when I have 3 different people all coming to me and telling me all this crap, I just get eat up about it and have no idea what to do. There basically is nothing I can do. There is no cure. There is no rescue available. I can't quit. I can't complain to anyone about it. And I can't make it stop. I'm so miserable and I just want that nasty woman to disappear.

Nothing uplifting today. Will try harder tomorrow.
