Not having found your people yet doesn’t mean you don’t have any. Some of them haven’t moved to your town yet.

A school is a small sample of humanity, assembled by postcode and year of birth rather than by anything to do with you. Not clicking with four hundred people who happened to be born nearby is not evidence that you are hard to like. The people you will recognise immediately are spread across other towns, other years, places you have not been yet.

In the meantime, go where the odds improve: a club, a team, a forum about the specific thing you care about. One or two is a full set, so you are not looking for a crowd.
