I've had similar situations with a friend of mine, and the first thing you have to realize is that it's not your fault and it's the person's responsibility to get help for themselves. I know you spoke of a "mental" institution and that is exactly what helped my friend out. If not going to the "institution", there are a number of other places that can assist her. There is nothing that you can do to change it, she needs professional help and in-patient therapy.

I totally feel for you and your family and wish the best on this one. My heart goes out to all of you.
