It is of my opinion that someone who consistanly speaks of suicide is practicing. They are thinking it, planning it, and are trying to get their courage up. Testing the water, so to speak.
Be a bad guy. Call a proffessional, get them involuntarily taken into the custody of a hopital.
Dont try to reason with them, they are unable to hear you. Dont fool around. Dont wait till they climb a watertower, bridge, make a noose or buy a gun.
(thank God for my sister, who pissed me off majorly for cutting to the chase, and caring enough to do something drastic).
Yes, this person is "playing" with you. Yes this person is seeking attention...See that you do it!!!!
