For me, I almost "tried" myself right into my own grave, so the way I help my son today is to pray for him each morning, asking God to take care of him.
People who haven't walked in our shoes have no idea what it means to tell someone that "they" are the only hope an addict has. If that were true, not one of us would be here.
We can love our addicted family members or friends, we can encourage them when they make positive moves to help themselves, but we cannot save them from that which is not ours to control.
Keep reading, keep sharing and keep praying, and you'll be okay.
