You can't "help" him, put you can just make suggestions to help him empower (sp?) himself.
Empowement not enabling.
Therapy, meetings, meds, whatever
You don't need to live like this and neither does he.
If he's anything like me he didn't even realise it was a problem until it was.
Im actually kind of shocked and bewildered because I thought I was too "smart", having witnessed the problems that existed in my family.
