I find it a bit strange people would stay here if it made them feel worse. Still, maybe they're trying to actively make themselves feel worse so that they want to CTB more.
I also wonder if people who say it isn't helping them whatsoever are being entirely truthful. What affect would it have on them if they were banned for instance? Or, if the site went down? Maybe it's true. Maybe it wouldn't affect them at all.
But, yes it helps me. Just to be able to be honest, not put on some act of being ok. Because, I've found it really doesn't help to do that in the 'real' world. (Be entirely honest about how I feel or, put on an act- it's exhausting.)
People either get very worried- which is pointless because there's nothing they can do. Which makes me feel guilty I've burdened them with that worry. They come up with ridiculous suggestions and platitudes that even they wouldn't/ couldn't follow... 'You're worried about your career? Become an astronaut.' Really? I'm not 5 years old. We don't just 'become' whatever we want to be! Or, they obviously avoid the subject- which means they clearly feel uncomfortable about it, don't want to be burdened with it, don't know what to say etc.- which again, makes me feel bad for making them feel like that.
I think these sorts of places are unique because, while a lot of people here are very empathetic. We may well have a degree of concern for one another, we don't exactly have so much direct responsibility for one another. It's annonymous so, in many ways we can't- even if we wanted to. That can be a relief for the person spilling their worst experiences and feelings. It can feel a burden to us to know that we've burdened someone else- someone we know that is. Plus, potentially changed the relationship- perhaps forever. People here have reported losing friends after being honest with them. Here, we can be honest and know that whoever reads our vents and some of the heart breaking stories that go on here- chose to read it. They don't owe anything to us. They'll respond if they feel strong enough to themselves but if not, they get the choice to avoid getting involved.
