Welcome to SR!!
I have everything going for me, and have had... the career, 4 wonderful kids... So how did my life become so unmanageable from alcohol?? I don't know, but I know it's because I am an alcoholic, for the last 6 months, a recovering alcoholic.
You ask how you are going to live the rest of your life without alcohol? Are you having fun with it? Are you coping with alcohol in your life? I wasn't.
Anyway, you just don't drink, just for today, then do it again tomorrow. The answers will come... A recovery program, and SR, will help you along the way.
