My friend has been going through a very rough time, messy separation with his wife, drug addiction(s), general self loathing and has threatened to kill himself before. I have talked him down from the ledge a few times, once I thought he had gone through with it and shot himself, I went to his house but he didn't come to the door, couldnt see through windows, anything. He claims he passed out drunk and slept through my attempts to contact him. He has since made similar threats, but none that I thought were serious, nothing specific. today he texts me "Im done. I just ate a handful of Klonopin. Peace". It felt real, I called 911, cops, emts, a firetruck, showed up to his house, he didn't answer the door. They couldnt do anything as they couldnt see inside. A few minutes later he texts me "never contact me again" I said "for what, not wanting you to die?" we proceeded to go back and forth via text and i eventually just blocked him. The guy has been one of my best friends for 30 years, he is like a brother, but he is manipulative and a liar. He needs help. I cant give it to him anymore. I knew he would be pissed, but i thought he was going to die. I dont know what to do.
