I talk to a LOT of people about this. But I am not a professional.
Tip #1: You have to stop beating yourself up over it. It's brutal. I get it. At my lowest I woke up for months wanting to eat a bullet. If I had better tools and coping skills I wouldn't have as close as I did.
Tip #2: Know you want to quit. Know that you CAN quit. It doesn't have to be today. But there will be a day.
Tip #3: Acknowledge that it's difficult and that you're doing the best you can.
Tip #4: I hate AA. I still think it's incredibly helpful for a non-insignificant number of people out there. I'm an atheist. I never bought into the steps. But the stories... hearing people say things that I'd never been able to put into words... was life changing. I wasn't the only one that couldn't put it down. It helped to hear that in words that I can relate to.
Tip #5: Get a mindfulness practice. I think a blend of meditation and stoicism (per William B. Irvine's book) is a great start. Skip the meditation if you have any trauma unless you're guided by a professional.
Tip #6: Make new friends, cut back on the old ones
Tip #7: Hobbies. Find some.
Tip #8: Keep doing what you're doing: asking for help.
Good luck. I hope you find your groove. My life is so much better today because I don't drink.
