Scarlett O'Hara

I have this stupid bitch that sits beside me at work who's on my team. She constantly complains, moans, puts whoever is next to her down and is on a major power trip. She thinks she's the best and will not shut the fuck up. I have to sit next to her crap every day and she needs to a)lighten up and b) stop acting like she's above us/has authority.

Can someone please explain to me how I should deal with this? I need advice before I do something stupid like a) punch her face in/bury her or b) scream at her in front of the entire office c) shoot myself.

Yes I've been drinking, but only because I needed to unwind.
