Hi and welcome and thanks for sharing with us,
NA has the same solution as AA but for addicts. It's got to be worth a try rather that put your family through that pain again, as you say.
You will meet people there who know exactly what you are going through right now. You will find friendship, love and support and be shown a way to live free from the drugs.
I do hope you can find yourself a program of recovery. Recovering from addiction on your own is very hard, usually impossible for most.
