Hi there MrsFox, and welcome to this wonderful website
I am terribly sorry about your Mother. My parents were also alcoholics, and the last thing in the world I would ever allow was for them to come in contact with my daughter, and later the grandkids.
The way to deal is to first educate yourself about this disease. You can start right here on this website by reading thru the "sticky" posts at the top of this forum. There is also a great deal of information "next door" at the other "Friends and Family" forums in their own sticky posts.
Another great place for information is at meetings of al-anon. I have found them to be invaluable. They have wonderful books and pamphlets, as well as kind and compasionate people that can share their own experience with their parents. You can find them in your local phone book.
Welcome again, I'm glad you decided to join us
Mike
