You really need counseling to deal with your issues.

And you need to not involve yourself in your parents divorce.

Just like their marriage was theirs to do with as they wanted, so is their divorce.

You do realize that your father isn't blameless, don't you?

From what you have written BOTH of your parents are alcoholics. And, unfortunately, BOTH of them had a negative impact on you and your siblings lives.

Have you heard of Al-a-Teen? It's for children of alcoholics.

And, yes, you do need therapy. And this is coming from a person whose father is an alcoholic. You are clearly angry and have issues that you need to deal with.

BTW, I do think that you are angry at your father, too. And one day, you will have the maturity to understand that placing him on a pedestal while villifying your mother for doing the same thing your father did was your way of trying to make sense of your childhood. It was hard growing up with one alcoholic parent, I can't imagine how horrible it must have been to grow up with two.
