Welcome Buckeye.
Alcohol plays a nasty game with some of us. It does not play fair so once you figure out your starting to lose... Best to get out before you get hurt too bad.
It can be done, you can quit. There are many ways to do it; AA, AVRT, SMART or a combination of things. The most important thing is to take it off the table as an option. I know I tried to control my drinking and always failed. I quit, and that was much easier. I don't know why but after the first sip I lose all restraint.
I too was a binge drinker. I had a job, friends, partner. From the outside no one would have thought I had a problem. But I knew it was killing me and I would lose everything if I continued down that path. I am so glad I quit. Life is getting much better and I am finding new ways of dealing with stress.
Being a bartender may be hard at first, but it may also be a blessing. You get to see people at their worst due to alcohol and realize this easily could be you. It can be a nightly reminder of why you quit.
I wish you well.
