I would go so far as to say you really can't rescue anyone but yourself. I'm not saying you can't help another person when they reach out for help. I'm talking about that codependency trait where you try to control another's life and do everything for them. You can't, they have to help themselves or they become what's know as learnt helpless, basically incapable and perhaps unwilling to help themselves. Le these people grow-up, give them the respect they deserve to live their own lives as they see fit. Place your focus back firmly where it belongs, on you.
