I am 39 yo and I am not close anymore to any of my HS friends. But I am very close to lot of my University friends. I don't think you need to worry about missing something irreplaceable for life. Also, do not take other people's memories and nostalgic feelings at face value. These memories usually filter out the bad, boring, irremarkable stuff to make the past sound like an anime. Also, it is often compared to struggles they are facing in the present and wish they could escape. All that said, I think you do should do something to not feel solitary. I am not so sure that friendships must develop naturally. Sure, they can't be forced, by I think they can (should?) be consciously pursued. That's my approach to keep my best friends close in my adulthood. Keep an eye open for good people, people who are kind to others and that happen to have some common interests with you. And if the interest seem mutual, make an effort to hang out with those people. For me, the bottom line: make an effort to be nice to nice people and nice things will happen
