Rescuing (over-functioning) is loves closet counterfiet.  It feels like love, looks like love (at first) and might even sound like love, but it isn't. 
An accurate definition of rescuing could be:-  One who helps because of their own need to be needed and does for someone what they should actually be doing for thenselves.  Beleive it or not, it is possible to be kinder than God Himself.  It never helps to rescue someone from the conseqeunces of their choices,  This is a 'must' teaching for most mothers and for all those who want to empower themselves and others.
