Just stopping you from ctb isn't helping you, it's prolonging your suffering. If they would stop you and then actually help you, that would be a completely different thing, but they don't. They stop you from doing it, throw you in a psych ward, dust their hands off, and say "There! I've done my part".
I think if you get saved by someone, they should be responsible for you in every single way that you can be responsible for another person for the rest of your life and theirs. They should be responsible for how your life turns out from then on because they were the one who saved you and forced you to be alive. I think if more people had to actually take responsibility for the person they saved, far fewer people would be forcibly saved. Because they're not doing it because they really want to save you or actually help you, they're doing it because they want to make themselves feel better.
