Welcome to SR, Sister. I too am the mom of an addict who has been in and our of recovery (presently out and missing for 4 years) and I know your pain. This program and live meetings saved by life, literally, so I hope you'll stick around and also try Naranon or Alanon or CoDA, all terrific programs that help most of us here.
There are many moms here who will be along to welcome you, and a whole group of people who can share what works for them.
Special prayers for you son, may this be the turning point for him, and prayers for you too. It's hard being the mother of an addict.
Hugs
