Remember, if you are in the US at least, and someone tells you they aren't ok, and you recommend a crisis line, and they mention anything regarding suicide, they are very likely going to be extracted from their living situation by physical force and end up incarcerated against their will, at very high expense to themselves, potentially in a way that could lose them their current housing or employment.
If their life was going poorly before that, it sure won't be better after.
The record of this could follow you around for life as well.
I understand this is considered conventional wisdom to recommend these help lines but I really think you should rethink that.
