Tough.
Stories like these I get fucking angry. Saying BS like "you can't leave" and forcing you to take meds, those fucking twats should STFU and stop "saving" people, all they're doing is keeping in their own agony and torture, if they want to die just let em fucking die, what's the whole big deal about death anyway. If they really cared they'd let you die. They obviously only care about having you, your body, around, and apparently get a fucking kick out of torturing poor people who just want a peaceful, painless way out of here.
What needs to be done is helping people the right way before they go ahead and try to CTB. Once they're at the stage they're actually trying to CTB, there is no sense torturing those people and forcing to live a longer duller. worse life. They need to either give proper treatment or let em go.
And what I have said above obviously only applies to people who have disorders and are being caused to CTB because of it, if people are genuinely curious and want to know the truth about what's beyond, those people should not be stopped and, if anything, should be honored to be brave enough to see what lies beyond. And if they come back, perhaps they can tell us about what they've seen, if anything, and give the rest of us a great insight. Even if it's just one person's encounter, though, there's nothing saying another person will have this encounter, and so on. It should give the rest of us a lot of insight into what lies beyond, though, and if they don't come back we should just wish em well wherever they end up, if anywhere.
