Me and a good friend have been in a rather heated discussion that has ended with multiple things: Us no longer being friends, and him saying that he shall get back at me for what happened.
A week ago, my friend told me that he was chugging tequila daily (he's 16) and many other horrible things(such as his suicide attempts) after I got a new phone and told him about it. I tried to help him with the situation, by telling him that I'm always his friend and that he should get off of it and that he could come to my home to let off steam. It didn't really work and I decided to go to sleep. When I woke up around the afternoon, I got news that he was recently dumped by his girlfriend. This caused him to be homicidal. He told me that he had a gun and that he was going to murder people he had scores to settle with, and that he doesn't about whatever happens to him. I tried convincing him not to, but after him saying that he must multiple times I decided to call the police. After a bunch of things happen, I call the police a third time with more information and was given information that they already had deputies at his apartment.
A few weeks later, he learned that I called the police and told people about his problem and what was happening, and now he's pissed at me.
Very, infact. He says that it has ruined his life since he has been sent to rehab or jail(Not sure to be honest) which has cut him off from everybody he loves. He's called me a horrible friend for doing that and, in his exact wording: "I will get u for this, for everything uv put me through". I was pissed at him also during this conversation, and since he normally calls me a spineless pussy, I told him that I did not care for him anymore, did not want to hear from him anymore, and that he could go suck on a chode and suffocate for all I cared.
I can't fix this since he has blocked my number and I'm changing my phone number in case he's serious. So, my question is: What in the fuck do I do? He doesn't know where I live since I've recently moved, but he could track something like my phone number.
