My best friend from college, who I lived with for 2 years and was really the only close friend I've ever had (we had a falling out at the end, stupid 22 y/o girls), technically died of alcoholism at 33 (she lived with end stage liver disease from age 30). When I found out, however, we hadn't spoken in years and I had looked her up because the night prior to me finding out, I had a dream where she came to me and said goodbye and killed herself in front of me. In trying to figure out what happened (I woke up, googled her, and found an obituary noting her death from a couple weeks before), an old mutual friend of ours told me, "Ultimately, she killed herself," which I took for literal suicide vs the slow suicide of alcoholism. I didn't find out till a few weeks later that it was alcohol. That entire experience was quite recent and I have been stuck in a paralytic depression for over a year, and my suicidal ideation is getting stronger as my life is getting worse. IE, more and more reason to do it every single day.
A few months after that, I found out via watching a recent Netflix documentary that one of my closest internet friends from over the years took her life back in '15. That really destroyed me, especially as we had frequently spoken of suicide and having a pact, but I had started to do better and had distanced myself. The last time she had reached out to me was the last time I was suicidal, and I never responded to her. It still destroys me. I had some contact with her family after she passed, her mother sent me the longest letters and her poor mother is so distraught, but I stopped responding because I feel so responsible and so terrible. I am a horrible person and surely nobody will be upset in the slightest once I ctb.
