Been there an I timed my quit, too. Folks don’t understand how hard the week before can be. BUT - drinking made my PMS 10x worse. Since I started trying to quit and getting 30 days here and there, I noticed a big difference. Now it’s almost gone.
So I get that it seems impossible to quit when you’re in the worst of the cyclical depression, but one of the things that improves that depression (at least for me) is quitting.
Good luck, and you can do this!!
