I had to cut this down a lot.

New Year's 2017, my ex (A) broke up with me right before a party we planned. They broke up with me with their boyfriend (B) in the room (polyamory), even though I begged A not to involve him. At the time, it was because I was clingy and overly jealous of B which I agree was an issue.

A month before, they and our mutual friends C and D all made a group behind my back "for a safe space away from me to talk about my issues". They never told me what issues they had.

B and his friends were shit talking me at school and my sadness turned into anger. I was in a server to talk to other friends and move on, and my first overly questionable thing happens. I was in our vent channel, and I drew me stabbing B to death. B came to me later about how I threatened to kill him. I was confused on how he found it, since I shared that where he shouldn't have seen it. I found out that C was leaking the logs of that chat.

A B and C would continue to vent about me on Vent (a social media app for talking about your emotions) with aggressive posts about how "abusive" I was, until about April 2017. As far as I knew.

Between then and now, we had a few good conversations. I still had anxiety seeing them.

April 2018: I got a job at a hardware store, and it turns out A was hired the day I came in for orientation. I had an anxiety attack. I vented about it and told my friends about it.

Later, A informed me that them, B, C, and D moved in together. A, B, and C started dating.

I was discussing plans w/ D to get my pal Z out of his impoverished home, but D went radio silent on the both of us. However, he was constantly posting art with the rest of the house. 

A week later, I get a desperate call from Z.

D broke up with Z because "he was an abuser", and now everyone in that house is fuckin. I. Was. Angry. They pulled the exact same shit on Z that they did me.

B messages me, saying I'm "getting myself involved with someone who will strip me of all my money". I call his BS, and he starts sending me screenshots of Z and B saying "shit" about me. All the things said in those screenshots were things Z's issues that have been handled.

I check his Tumblr, and it turns out he was talking about my vents.

I proceed to make a vent that says, "How can you say I'm not over it when you guys are stalking me?" Then brand new accounts made that day comment, made by A and B to rant at me. Are you kidding me?

Z and I start looking through the accounts and they all were talking shit for a long time now.

It became a war, me flinging their hypocrisies and questions at them, while they sling insults.

It came to a climax of me posting a joke OC on my deviantART, making fun of B's horrible art, all of them getting engaged after a month, and their behavior. B sent me death threats.

I reported the death threats to work.

All of them have been posting shit since saying I'm a dumb lazy whore.

To put it simply, AITA for retaliating?
