Welcome Charlie - I'm so glad you found us. Being here will help ease your anxiety - you're among people who truly understand what you've been through.
You sound motivated and determined to begin your new life. I don't think you should belittle yourself for not doing this earlier (I was in my 50's). You are taking action now & that's what counts. Some never realize that drinking is sucking the life out of them. Be proud of yourself and keep posting.
