I'm so, so sorry you're dealing with this.
i cant help but get frustrated and yell back he has thrown the strainer full of dishes at me locked me in my room kicked my dog
This is abuse. I would consider contacting the police the next time he is throwing a drunken temper tantrum. I think it's great that you are getting out ASAP, but I am also concerned about the other people and pets getting the brunt of his abuse. This may seem extreme, but abuse is extreme.
I'm so sorry that your mom, for whatever reason, is not in a place to deal with this in a more forceful and productive way. Children deserve the protection and defense of their parents.
