You should seriously understand what you are signing yourself up for if you call one of those numbers on yourself or someone else.
For one you are volunteering that person for involuntary incarceration in a mental health facility for an unspecified and potentially unlimited amount of time.
Need to show up to work tomorrow to avoid losing your job? That probably isn't happening.
Need to pay your bills to avoid losing your house? That might not be within your capabilities for the next several months or longer.
Kids need to get to school? CPS is likely going to be handling that for the indefinite future if they don't have another guardian because you aren't going to be around to do it and you are no longer fit to be a legal guardian anyway.
I'd probably rather end up in Jail than in that system.
Simply put, in our society indicating you are suicidal is a defacto crime and you should never do it(including and maybe especially to a psychiatrist/psychologist who maybe taking on legal risk if they don't institutionalize you after the admission) unless you are ready to suffer the consequences.
