Is it too late ?

I (21M), recently graduated and started working at a big 4. Life has really been lonely all my uni "friends" aren't in touch and i work mostly from home so absolutely no human contact. I go to they gym every morning no matter how much I try to socialize it just doesn't happen, it's like I've forgotten how to talk to people, either they have their own group or I feel like they don't wanna talk. Maybe I'm overthinking or idk life's really hard after grad, I am so cooked.
