Two things that I think are way more common than most people realize because few people want to admit to them is having a period of time where you have no friends & never having really dated someone well into adulthood. The second one is observation but I find when I tell people a few years ago I had no friends it ends up resulting in them telling me that they also used to have/currently have no real friends. When I first was getting social again and felt like a feral child raised by wolves while all my peers had moved on w their lives my therapist told me “most people are as lonely as you are” and at the time I was like okay cope 😑 but now looking back she actually could not have been more right
