Break up

Me and my wife have been struggling for a couple of years now. I suffer from severe anxiety and depression. I've not been as faithful as I should have been but I've done alot of crap when I've been drunk. I'm now back at my parents for a bit. Me and my wife still talk but we're very short with each other, I get very frustrated and angry and it's pushing away any chance of reconciliation. I need some kind of help or tips to cage my emotions up. It's weird because I have no emotions for anything else! My wife always targets me and blames me for the arguments but she speaks to me like she's just trodden in me. And everything is my fault which obvs doesn't help with my mental health. My daughter is keeping me alive right now.
