But auto-erotic sex and vampirism have nothing to do with it, BTW.
Sucks....
Sadly, I think it’s because its fairly quick and someone can’t come rushing in and save you. Drug overdose, stomach pump. Use a gun, no guarantee you will not end up on an operating table. Cutting yourself, very hard to do. But tie a rope and hang yourself, permanently done. I think some of them are auto-erotic, and I don’t know anything about vampirism but I truly believe it’s the quick finality vs. risk of being saved by someone that is driving the methods. Breaks my heart whenever I hear of a suicide, such a terrible waste, and just thinking of the level of desperation is unbelievably sad.
