sbroughman, I'm not an addict, nor am I in recovery; but I have a number of alcoholics in my family so I know the disease well. I consider myself lucky in some ways: I'm one of those people who becomes violently ill from alcohol and have adverse reactions to many drugs so neither have ever appealed to me.
I just wanted to offer support and encouragement to you. Your state has a nurse assistance referral program, find out about it and get involved with it ASAP.
Keep working your program. I'm glad you have some peace now that your secret is out. Professionally you can come back from this; but first you do have to heal and work on the disease. You can do this; you aren't the first, nor will you be the last healthcare professional who has this disease and is able to return from it.
Good Luck!
