What is this feeling?

Fucked up

Someone made fun of my friends weight this week. I'm super fucking pissed about it.  Like you don't make fun of anyones weight no matter what. DO YOU KNOW HOW BAD THAT CAN MAKE SOMEONE FEEL. I GET BODY SHAMED ON THE DAILY FRIM MY FAMILY. AND IF YOU AND YOUR LITTLE FUCKING FRIENDS THINK ITS OKAY TO DO THAT, THEN YOURE FUCKED UP! I was laying on a bench and when I heard what this bitch said I was pissed he goes "*** is round." And then he tries to save it by saying "well we're all round." I stood up and started yelling at him. I was shaking with anger once again. I said "do not ever say that again, do you know how insecure she is about that shit." I kinda just repeated it in a different way a few more times. She's going through shit right now and doesn't deserve to be treated like that. The only time I start shaking out of rage is with the shit he does. Yelling "cock sucker" at me in the hall, PUBLICLY wishing death upon me, making a whole discord server just to talk shit about me, causing me extreme stress and anxiety throughout our whole friendship, being racist. You know the usual. People had to tell him to apologize to me about what he said, I was shaking so bad. I was afraid I might hurt him or myself. No one else has pushed me too that point. I will never  be his friend again, and that's a promise. I get disgusted when I look at him. The way he acts it putrid. In my opinion.
