ffs y'all there is no timeline for your life, there is no schedule. there is no entity going "you're 25 you should be out at the club partying" and "at 26 you should be hustling and building your career" or "if you're 30 you should at least have gotten married and had two kids already"
there is no universal timeline for human growth and development. yes we are put through education at certain ages but even that is flexible (I was skipped past kindergarten so I was a year younger than everyone in my classes). you can take a gap year after high school before college or not even go to college. you can be an introvert and not enjoy going out in your 20s -- and you shouldn't force yourself to just because you believe that's you're "supposed" to do. just because other folks your age may enjoy the thing doesn't mean you have to do it if it sounds repellent to you.
I beg you to think about whether you actually want or need to do the thing that you think society expects of you. you don't have to have kids if you don't want. you don't even have to get married if you don't want!
I never, ever got the point of going out partying or dancing. I'm not a sociable person. I would rather have a quiet night at home or with a few close friends than in a strange place full of nothing but strangers. getting out of my comfort zone HAS been worth it and there are times you should push yourself. but you don't have to be on the same timeline as everyone else. you're allowed to chart your own course.
I can't say I'm a perfect example because here I am at 51 with no job and no career training, no real idea where to go from here, but I've done interesting stuff nonetheless. do I regret not finishing college? sure. could I go back and finish it? probably, actually! (even though I still don't know what I want to do when I grow up...) but I never wanted to be a mom, never really found someone I truly wanted to be married to -- though again, that's not to say I never found love.
just... don't stress about it so much. you will be happier. I promise.
