Feel weird nearly a week after drinking

I am not a big drinker at all and rarely get actually drunk, last Friday tho I over did it and was pretty toasty and up till 6AM. Saturday I had a bad hangover but the physical issues were resolved the following day. My perception, reality, and thinking still feel off 6 days post night out however and it’s almost as if I’m living in a hazy dream or things aren’t real, kind of like a feeling of being high in a way. I have brain fog, feel lightheaded, am still exhausted, have difficulty concentrating, and just feel like a much more dull or less fun version of my normal self. Has anyone experienced this and how long does it take to wear off? Is there anything to help speed up the process? Thank you!
