No, because the implication would mean there should be an obligation for someone who joins a site like this to kill themselves within a certain time frame. To kill themselves full stop. That would actually be a cult and I don't believe it's what the site is or should be about. It's a safe space for people to discuss their feelings about suicide or, anything else- pretty much.
That said, I do fear making a thread about an attempt and failing. Not that I think people would be unwelcoming on my return but, I just don't fancy the emotional rollercoaster. I think it more likely I would post a scheduled delayed goodbye to avoid that though. But, I've only ever seen people be welcomed back as far as I recall.
People sometines get peculiar when SN attempts supposedly fail. That's one exception. I think because it scares those of us who plan to use it. Plus, people are concerned about pro-life infiltrators spreading misinformation/ fear.
I suppose it's actually weird for me not to feel more uncomfortable here. I certainly do in real life. I sense I'm boring people, irritating them, depressing them, worrying them. I'm very sensitive to that in real life. Here though- I feel like it's a choice. No one has to continue reading my thread if any of the above applies. They can choose to ignore it or, even put me on ignore if I piss them off.
So, I'd say- you do you. So long as it isn't harming anyone else. Some people will relate, some won't. If they get unnessesarily pissy though- just ignore them!
