<human>: Could you distill the essence of the text into 1-3 sentences?

I started a job at a pizza place last October, not ideal but its flexible for school. So there's this girl that works there who's really nice to me. I was entirely oblivious to the fact that she thought I was cute until the Christmas party rolls around and she was basically all over me. At first I was standoffish because I work with her and she seemed kinda like a bro if you will. She isn't super cute or anything but she does have some massive boobies. And as I kept drinking, the desire to plunge my face betwixt her voluptuous fun bags grew. Sure enough I caved and we shared a cab to her place for sloppy drunken sex. So fast forward to now, I have since discovered she is a HEAVY drug user. Cops were called on her last weekend because she was wandering around aimlessly in a bad part of town at 6am. Now whatever I say is taken as an invite for her to start flirting with me. And when I hang out with her and my other work friends she just keeps trying to hang onto me. I've told her I just want to be friends before and I doubt she even heard it. And you can forget about flirting with other women while she's around.
<bot>: Wacko drug addict I work with has a hard case of the feels. How can I permanently friend-zone this girl without having to quit my job or faking a relationship. All serious replies are appreciated.
