When your meaning in life is to fix someone else’s life, we may call it “co-dependency” but it is really idolatry. An idol is whatever you look at and say, in your heart of hearts, “If I have that, then I’ll feel my life has meaning, then I’ll know I have value, then I’ll feel significant and secure.” There are many ways to describe that kind of relationship to something, but perhaps the best one is worship.
