You need to leave this woman (or have her leave) and take care of yourself and those kids. Get out of this harmful situation. Protect the children and yourself from her drunken insanity and abusiveness.
Staying with her will not fix her problems.
You need to find the courage to leave or ask her to leave, if not for yourself, for the children who do not need to be further damaged by your wife's destructive addiction.
ETA: I agree with Least--probably would be best if you could get HER out of the house and you and the kids stay in the comfort of your home.
