What do other family members say? In this type of situation, normally a united front is best, and then a family action plan should be put in place. It's very hard for one person to be the support network of someone who is either an alcoholic or suffering from mental illness. In fact, it's almost impossible.

If you don't have other family members to talk to about this, then I'd suggest talking to a mental health professional and describing the symptoms and ask for real advice. I don't know what the rules are where you are, but if the person is violent in any way and the police are called, you can have the person committed for a period of time for assessment. This is obviously not ideal, but sometimes can be a starting point in getting the person to realise that you can't deal with their issues alone anymore.
