I feel like crap, kinda, but at least she's gone

So, my ex-friend Carolina (13F) is really toxic and she just declared our "friend breakup" very rudely a few days ago. I am trying to recover as she had been my friend for two years but was just pretending the whole time and wasn't who she said she was. The first step was to get rid of contact, the next step is to try and forget about it, which I'm trying to do and trying not to think about.

She was following everyone I was following and said hi to my friend "Frankie" (15NB). Frankie asked if I was the "ex-friend" I told them about, since her name was in her username and I said "my ex-friend Carolina (not her real name). She said she was and that she hated me.

She also said I could die and that she didn't care, and that I was her "dumb dog" before Frankie also blocked her. Later, they checked her account username on a different account and it was gone and she supposedly deleted her account???
