I don't know how I can go through the day without talking to somebody at work. I work on an assembly line and if I just focused on my job and didn't socialize with people it would drive me fucking crazy.
Of course I was kind of like you in my early twenties to where socializing just wasn't my thing and I worked third shift at a grocery store. That was without a doubt the most depressing 2 years of my entire life. I would work 10:00 p.m. to 6:00 a.m. go home, sleep, wake up, watch anime, eat shit food, go back to work rinse and repeat and I didn't talk to anybody.
I changed jobs, got married, have kids and I'm much more social at my new job and it's a much better experience. I worked with a lot of older guys who were just massively antisocial dick heads and I didn't want to be that guy at work. Trust me you don't want to be the guy at work to where when people come in and see you they instantly dread their day.
