I can only speak for myself but where I was had my family did that to me I woulddnt have hit my bottom. I would commited suicide instead.
If you were wanting to confront your dad from a place of love rather than your anger I would definitely encourage you to sit him down and tell him how you feel. But, your anger is so great it is dangerous to your own health and confronting him from that anger would probably be an emotionally dangerous thing for both of you.
You cant force a person to hit bottom. It is a unique situation for each person. There are millions of recovering alcoholics globally and if you could ask each one what their bottom was you would never hear the same story twice
