Heavy drinking for 4 days in a row and digestive problems??

I’ve spent 4 days partying and drinking aprox 4 drinks of vodka per day for 4 days on a row that were strong and i’m not used to drinking a lot aproximatly 2/3 times a year. Now i’m back home 3 days later with a discomfort in the upper part of my stomach like i’m burping all the time feeling also full and bloating as hell. I’m so scared something is wrong with my body im 28yo .. could it be my liver failing as i read in the topics or something similar bad.. i’m so scared can’t sleep at night and regretting so much never ever again would i do it again. Can’t go to the doc before 1 week wich seems so long for me to handle… help if u lived something similar..
