Is OTHER wrong in the post ? POST : She was in high school, the ,,take drugs and look down on people“-type so she wasn‘t really my friend then. But I always thought she was somewhat interesting/ secretly a good person, because she had a rough childhood after all (no excuse though) and something told me she wasn‘t that bad after all. 

Years later I met her in adult life and we exchanged numbers. First I thought wow she really changed, and we met often and had much fun. In only few weeks we became very good friends.
(My other friend mentioned she may have borderline because she has this two extremes with friendships.)

Soon I would notice how she drinks every day, smokes a lot of pot and becomes angry to the point that she destroy things in the living room, broke her foot in a tantrum, and fights with strangers.

But when she sobers up again, she tell me this isn‘t her, that it‘s the alcohol.

Whenever she is high on pot, she becomes a different person, more aggressive and possesive.

On top of all of this, she knows people that can seriously hurt your body (and mind). 

I realized too late that I was now way to deep in a ,,bond/friendship“ with this person, and apparently I‘m her only real friend now, which makes it even more difficult.
She often tells me how other persons ,,abadoned her“ for ,,no reason“ and how much she hates them. 

I tried to cut her off, by telling her I don‘t have time and so on. But as soon as I don‘t reply, she sends me so many messages, calls me often and so on, tells me she misses me, asks me what I‘m doing and so on.

(I know it‘s not the sub for this but if anyone has any tips how to cut someone toxic off is welcome)

She is also distant friend with a mutual long term friend of mine.

I don‘t want to get hurt emotionally or physically by her, but I‘m stuck now, I wish I never let her into my life. Now I‘m to scared to cut off the contact. 

And I don‘t have the physical or mentally strenght for any of her tantrums or abuse when I try to distance myself.

AITA for letting a person with trauma, possible borderline and trust issues so fast so close to me only to trying to cut her off after realizing she is rather a toxic person?
