Work Relationships Options

[Stephire]

I've been working at an Italian restaurant for two years.
For the first year and a half (or as little less) I didn't think much about work while I was not there, I went there and only talked to my tables and managers with a smile on my face, and then I cleaned the restaurant and went home.
I had no intention to make any friends or enemies; I didn't care and only used it as a place to make money.
This was pretty successful seeing as I banked and made no real connection with anyone.
Well after being at Primo's which seems like FOREVER, I've become a super win employee, winning dumb bullshit contests, being a constant Team Leader (I check and assign duties for all the other servers), and I used to train; but our training program changed.
So blah blah blah, work is work, I don't care, but then I accidentally become close to a boy who closed with me all the time and being the lolperson I am I go to Denny’s with him once after work and leave my then boyfriend to date workboy.
So things go fine for a while (except I break my ex-boyfriends heart, but that's a long story).
But working at a restaurant is different from any other place I've ever worked at.
The difference is-everybody is tweaking on something. I work with, like, 6 junkies, one of our old key managers had to take leave for checking herself into a methadone clinic, 4 of our cooks are dealers and illegal’s, I mean if anyone has ever worked at a restaurant, they would get what I'm trying to say. It's drug hookup central.
So obviously, my new boyfriend introduces me to the world of wonderful Buddha.
But I gave up on that after a couple of months because I gained ten pounds and I really don't look good over 125lbs.
Anyway, one of the junkie girls at work thinks she owns all men and ever since I've been dating Jacob has a personal vendetta against me.
I'm a quick to anger type person and every time she gets in my face she makes me blow up.
She very tactful too, like she'll instigate and then when a manager steps in suddenly I'm the bully. This is gayzors. I mean, I'm somewhat of a bitch at work, don't get me wrong, you'd have to be to work with the heroine whores there. It's madness.

Well...my question is this through this long situation of lame, how do I fix my work relationships?
The girl who hates me just won’t stop, and I'm over it. I don't know how to patch it up. I'm so ignorant to apologies and how to make people like you. My boss' say my bad attitude towards the other employees is the only reason I’m threatened with being fired. It's so annoying, she acts like life is mean girls and she's the Regina to my Lindsay Lohan. I mean I could just quit and look for a new serving job, but damn her winning like that makes me want to scream. I also don’t feel like learning a new menu, etc.
