I have a friend who wants to kill herself. In a very violent way. And I can’t seem to talk her out of it.
If you think that she is a danger to herself (or others) then you should call the proper authorities.
^very this. She might not thank you for it but it will give her a bit more time to rationalise these compulsions. Theatrical suicide attempts tend to endanger people other than the instigator. You may save more than one life.
