Make a Plan
Here’s where it gets hard, because there is no right solution, and you can’t know the appropriate approach until it’s over. There is, of course, the intervention: when you gather together family and friends of the person and you all publicly confront the person with his behavior. Everyone either expresses a way that he/she has been affected, or reads a letter, or does something that ultimately communicates, “Dude. Uncool.”
The intervention is the most extreme approach, and isn’t right for every situation. It can be when a person is in danger of either hurting himself or hurting someone else –by suicide, recklessness, or severe substance abuse. In some cases, police may even need to be called. As much as we’d like to be able to force a sibling or friend or parent into treatment, we simply can’t. They have to meet strict criteria for being committed involuntarily to an inpatient hospitalization program.
Someone has to prove that they are incapable of meeting their own basic survival needs (paying bills, proper hygiene, nutrition) or that they are a danger to themselves or others. States vary with regard to the criteria, but it is not easy to make the case because you have to bypass all those human rights and stuff that we have.
