I can relate but lack of socializing in college didn’t bother me (I’m an introvert). Didn’t make any friends during undergrad and made some friends during my grad program that I still talk to but most of my friends are from high school.
Everyone’s college experience is different and just because it didn’t check certain boxes (unless they’re important to YOU), that doesn’t mean you failed. I think it’s put out there to be this special time in your life but “special” is subjective.
