Brain Fog week after drinking?

A week ago a friend of mine hosted a party and i got absolutely wasted. I drank way over my limits and i knew that. The first day it was alright, just a normal hangover, but as the days progressed it didnt go away. I couldnt concentrate, felt like i was on autopilot and the fact that it took me time to actually process what was happening around me. It all felt like brain fog. I’ve read up on it and many studies say that it should pass for 8-24 hr or a month if i’m an alcoholic, but i am not. I have chronic anxiety and I’ve been driving myself insane with worry if i’ve broken my brain or something, going as far as to think nothing is real and that i’m in a dream-like state. Is brain fog normal to last this long after a night of heavy drinking? has it happened to anyone? My symptoms have been lessening over the last few days but im still so worried
