I have a question for you: do you just get used to suicide ideation after awhile? I can't even imagine living to 65 years old. That number seems like a magical fairytale to me.
It would really suck to live that long against your will. Do you eventually accept life for what it is?
Based on their post and lack of content from op. I'm pretty sure they are her mostly to tell people that others love them and they shouldn't die.
Like I have doubts they are her for any other reason than to browse or to "save" people.
Anyways, I'm about half their age and to answer your question. I found its situational. Like hope is a double edge sword. Sometimes you hope for a better future and push for it, and you get it. Sometimes it's the same as before. And sometimes it's worse. In fact, most of the time it's worse based on my experience.
Anyways, I think some people find that thing to attach to so they have enough motivation to live. Sometimes it's good like living for their kids, and other times it's stupid like being able to see the next TV show. IMO if someone really wants to die this second, it isn't that hard with the info provided here. But I think most want to test if they will be more comfortable or less before they die. Like I think most are on that verge and if they become more uncomfortable then that will push them. But if they become more comfortable, then they have more reason to stay alive. If they stay the same, I think sooner or later they will adapt or die.
