Summary of the storm

A coworker tried to turn me into a laughingstock when I joined thile office 2 years back. Following this, my friend started to hang out more with them and started to ignore me. This bothered me and triggered my borderline. I shared with my other friend (who became my favourite person - an unhealthy borderline attachment). I wanted my favourite person to treat the other friend the same as she had treated me, by creating this weird gang against me to bully me. He never listened, and it caused fights. They all thought it was "toxic" of me to treat her the way she treated me. Finally they're all friends and I was slowly isolated. Now they all treat me like that. I'm the bad guy for retaliating. They would always unite to treat me badly if I retaliated. And yet I was the toxic one to ask my favourite person to unite with me because they treated me like sh.it. How come it's justified when other people do it? But not justified if I want to take a stand for myself and to ask a friend to take a stand the way they would all stand against me? It doesn't make sense.
And now I'm friendless. And they're all friends. And they all treat me like shi.t
