These things sometimes happen in clusters---someone who is struggling with ideation hears of a successful attempt, and decides that's how they'll do it too. My high school is (in)famous for having kids kill themselves on the CalTrain tracks, and that dates back to before I was a student there in the 80s.
As someone how has had his fair share of suicidal ideation in the past, speaking to anyone reading this who might feel the same way: You do not have to do this alone, and there are people who are ready to help. That's hard to hear when you are in the middle of it, but it is true. Heck, at last night's meeting, a good friend said something like that, and my brain immmediately responded with: "No they don't." And, I am in a MUCH better place now than I was during the lowest point in early sobriety.
