Welcome, you've come to a good place. My son is an addict and I know your pain. I'm so glad you found a meeting, that will help you more than you know. Some good reading material is "Codependent No More" By Melody Beattie, it's a great book that explains so much about codependency in language we can understand.
Make yourself comfortable, keep sharing and walk with us on this journey.
Special prayers go out for your daughter, that she may find a good path and stay on it.
Hugs
