I'm not trying to dismiss anyone's suffering or pain, but a lot of goodbye/farewell threads I've read don't seem believable. Just the things they say or the timeline they post or little other things make me think they aren't actually trying to CTB, and they just want to read all the warm wishes from everyone else.
I will absolutely never say that in someone's thread, but I don't think the number of threads accurately shows the number of suicides.
