llm, Welcome to SR! As the others have suggested, stay awhile, read the others post, the stickies at the top. If possible get yourself to Alanano/Naranon meetings. f2f meetings literally saved my life.
I am the mom of a 30yo crack AD (addict daughter). It is NOT an easy road, however you are not walking it alone, we here at SR completely understand and will walk with you. (sharing our experience, strength and hope) (even our fears and tears)
Hugs from one mom to another.
Chris
