Hello Learning,
Welcome to SR! I am sorry for the circumstances that brought you here, but happy that you found us.
There are many members who have similar stories who will be along shortly to share their ESH (experience, strength and hope) with you.
What helped me the most was to figure out what was mine to deal with and what was his to deal with. What my A did or didn't do, whether he went to see his doctor or not, etc - that was his to deal with. When I got out of the way and he had to deal with his own choices, consequences, etc - well, it was hard at first but ultimately better for all of us.
Keep posting, reading - there is a lot of good information on this forum and also on the Friends and Family of Substance Abusers. Check out the stickies at the top if you haven't already.
Again, welcome. I hope you find the support and encouragement you're looking for here.
