<human>: When I was in college, I became friends with this girl, A. We were really close and became close with another girl, B. After a while, B got a SO and stopped talking to us. A is really bitter and likes to talk about people behind their backs, and proceeded to do so. We drifted from B, mostly because I listened to what A said and just tried to avoid confrontation. A and I moved into a place with a bunch of people, and she proceeded to be a horrendous bitch. The stuff she pulled was beyond low, and I still have horrible nightmares about living with her where I wake up panicking. She shit talked everyone, turned everyone against each other, took over half the house, threw fits, and basically made the apartment super stressful.

So we politely kicked her out. She proceeded to shit talk all of us nonstop, and of course went running back to B. Fast forward to years later, and I'm living very far away. They are the furthest things from my mind, except for my occasional sweaty moments where I remember how stressed out I was at that time and how terrible I always felt and how she always talked me into the dumbest shit.

B is talking to a couple mutual friends I barely talk to, but I think about how I'd like to be her friend again. We used to collaborate on projects and it was really fun, but I was told A is still really close to her...TOTALLY not worth it. 

But I find myself mourning the loss of our friendship. I know I'm basically talked up as an ass by A to her, there's no question. So...I'm just trying to move on from these people halfway across the country and I'm trying to not have panic attacks every time I think about what a shitty person A is. It gets easier, but there are still moments.

And now that is OFF MY CHEST. Thank you!!!

Could you distill the essence of the text into 1-3 sentences?
<bot>: Became friends with an ultra bitch in college. She pretty much stole away a friend, kinda missing her. Not worth it.
