"Yet, you don't see all of them venting about suicide,
threatening suicide or fantasizing about suicide in messages they have posted here."

Maybe they're not suffering as much as we. simple as that. or maybe our tolerance point is lower... yet I will tell you I have restrained myself in the past from such mesages for reasons you speak of.. that was when things were still bearable.. time comes when they're not anymore... and you want to scream as much as you can. try to understand that and no mean to belittle your own suffering but obviously you haven't been there.
