It feels like my life is collapsing

Life collapsing
Stuffs not been looking too good. My ex girlfriend broke up with me a couple of months back because she was upset with me being friendly with coworkers. I violated her boundaries. I was doing fine until I went to a military base for a reserve training session. We have history there. She told me she wanted a baby and all of these great things and then I found out she had been talking to another guy. I extended my contract and now I’m going to a war zone in 10 months, and I’m horrifically addicted to alcohol. When I found out she was talking to another guy, I got black out drunk with some friends and did some pretty crazy stuff. Nothing too bad, but at the very least concerning. I have been praying to God, but I just don’t see any response. I am whole heartedly a Christian but I feel alone.
