how do people function normally?

hey i’m 23 and i feel like i’ve hit a wall i just don’t understand how everyone else is functioning??? like idk i just find it so difficult,, every day is the same outside of part time work and socialising once a week, i wake up sit around smoking cigarettes until i have to eat and then i eat and go to bed, i find it weird that people just have to much to do all of the time it feels like people are acting?? like wdym you wake up at 8am do a whole morning routine eat breakfast and then just do stuff i never know what to do, i don’t enjoy anything i used to anymore, i don’t really have fun , i have no motivation to do the things i used to spend all of my time doing like gaming or reading or watching movies or going for walks i just don’t really care,,,,, how do i become an actual human being ,,,,
