Welcome! I second the recommended stickies (or should that be "third" it?).
We've all been in your shoes. None of it makes any sense. Alcoholism is just plain crazy-making for everyone it touches, from the drinker to the family, to the bosses and coworkers, to the family pets.
You'll find a lot of good support here, and in the rooms of Al-Anon, which I also recommend.
