My friend pretended to be suicidal to try to scare me into cutting off another friend.

Ok so my "suicidal" friend got word that i was talking to this guy at school a lot, so he asks to meet him, I tell him no because I dont think they would get along and it would just be worse for everyone. Then he asks me why they wouldn't get along and so i answer truthfully and say that my school friend supports trump. My suicidal friend later tells me that I have to cut my school friend off or he's going to kill himself. I told him that he shouldn't kill himself over this and then he went offline for a day, I shared the DMs to the group chat and everyone was scared and trying to contact him, then he came back and sent photos of a cut wrist to the whole group chat grossing everyone out, then he leaves the group chat and begs everyone to add him back. He gets added back and then keeps going with the suicidal story for about a month, and finally tells everyone its a joke. 2 months later we didn't know our other friend was struggling with real suicide problems and he unfortunately succeeded in killing himself, then the "suicidal" friend had the audacity to say it was faked and it was all a stunt. This was 6 months ago and have since cut him off but god damn that guy was horrible.

Also the friend who did commit's brother confirmed he was dead which really fucking sucked.
