grandma - for both you and Jenny, there is a thread for friends & family of alcoholics (and another one for substance abusers) if you look further down the original page.
That's what I call the F&F (friends and family) - there are double winners there, there are family members who are torn apart, family members who have come out the other side.
It's a lot of help. I did a lot of reading there, at first. Heck, I lurked here for about 2 years. I dipped my toes in this and that forum, but I found home in the F&F. That's just me. I'm also very active in a few other forums.
My point is - read around, there are a lot of forums and some of us fit in more than one. Post if you have questions. Read the stickies (the permanent threads at the beginning of each forum - invaluable) and believe in yourself.
If you don't believe in yourself, join in here, let us believe in you until you believe in yourself. A lot of us have been in that position, including me.
Hugs and prayers,
Amy
