Hello OP ! You do have an alcohol problem (like me!)
The feelings you have will 100% pass. Try and rest and push the self loathing away from your mind and be proactive about your future self. After the fist drink or even sniff of alcohol - in some people it can trigger a response in the brain that makes you want to keep going to till you drink far far too much. Its tied in with genetic make up and/or issues we have from our past.
My defining moment of giving up drinking was staggering around a roundabout on a motor way slip road at 2am in the morning. I had no idea where I was. Lucky a young women stopped and made me get in the car and drove me home. DH was furious as he had to leave the kids in bed and come looking for me as I had rang him crying. I am still not even sure which round about it was as there are two near me. Huge roundabouts that several motor ways lead to. I could have been early killed or feel in the embankment and no one would have found me.
There are lots of sober groups you can join, you can even log in to AA on line through 247 hours a day. I actually found that group very comforting after my round about incident. Its people from all round the world and you can just drop in and out. Its very very supportive and every one has the same story or even worse than you.You dont have to speak on it and can just listen. Even though you dont drink every day - that blow out binge drinking shows you do have an alcohol problem.
There are some great books to read about why people binge drink or why they have alcohol issue you are really not on your own.
Be kind to yourself today, you dont need to self flagellate yourself. Talk to your dh and tell him you recognise you have a problem with drinking and would like his support. My Dh didn't think I had alcohol problem as I wasn't drinking every day - just when events were on but most of them ended up the same way, me pissed and needing help to get home. He would just say 'just have two then stop' but I couldn't! After the round about incident he was fully supportive after he cooled down.
If I was you today I would log on to the AA 247 hour zoom meeting just to hear other peoples voices that are going through this or are coming out the other side. There are binge drinkers on there too. Honestly you are not alone in this
