How can I help a friend who has a bi-polar brother?

My friend's brother is suffering from depression and is bi-polar. On top of that, he is alcoholic. For the last 2 years, he has become worse and worse. Lately, he has had suicidal thoughts and he asked my friend, his sister, to kill him.He doesn't work and has no health insurance. He needs psychiatric help, though. He refuses to seek help. How can we help him before something happens?Thanks.

Sounds like her brother is trying to self medicate with the drinking. There is little you can do with an adult unless they are wanting to harm themselves or others, then they can be reported. (It may be a good idea if he is suicidal) The only thing you can do to help your friend is to be supportive. It is very stressful to have someone you love have an illness they will not get treated. As far as asking her to kill him, sounds like he's looking for some type of attention; very unfair to your friend.
