I would argue that if someone requires a shock to act like they care, then they are probably overestimating the amount they care. I don't say this to be a dick, but rather to point out that this particular argument sounds very hollow to a suicidal person. It's better not to use it. If the suicidal person is holding on because they believe that other people (mom, dad, etc.) care about them, this can make that caring seem trivial enough to stop considering.
