Thank you for all your responses. I have never seen the tv show, or been involved in an intervention before, so i don't know what to expect really. His parents and sister are all very worried about him and i think would be very willing to participate.
heartsmiles, thank you for sharing. I am sorry to hear about your situation. We have two 14 year olds, a 13 year old and a little one and my counselor was not sure if the teens would be able to be involved. We did decide that if they aren't allowed or choose not to participate, they could still write him a letter to know how he affects them and how they feel.
Thank you again everyone,
