Something similar happened to me. My friend called me at 2am. He had been going through a rough couple of years at that point and liked to call me in the wee hours of the morning while he was drunk to talk nonsense. I just wanted a night to myself from all the crazy so I ignored the call and went to sleep.

He died at about 3am. He killed himself, but we'll never know if it was on purpose or not. He drank too much and took too many pills that night. He drank and did a lot of pills every night, however, it could have just been the wrong combo that night. Or maybe he just said fuck it and did himself in. I'll never be certain. And that's the worst feeling.

He left a voicemail though. He sounded so sad and just wanted to know if I wanted to hangout. I could have possibly saved him. But I ignored him because I wanted a night off from him. Now I'll never see him again. It's been years, but I'm still guilty. I never left a call, text, or message go on read anymore out of the anxiety of remembering what I did to him. It's so easy to read a text and forget to reply.
