You can absolutely stop living the way you are. Last year I was exactly where you are in using beer as my 'answer' to everything. Actually though beer was the cause of so much of my depression, anxiety, insomnia.
The miracle you want will happen through a plan. When you start today, start it by forming your plan. Dee gave you a link. Another place you'll get a lot of help is the 'weekender's' thread started by weasel1966. Jump in there and ask. Joining the August class is a great start as well.
I have my own stumbling blocks when it comes to getting my mind around a higher power and am working through that in my life. But the first step for me had to be getting sober and building a solid life of sobriety. Start there and the rest will fall in place.
Wishing you the very best.
