We might think that people are born with social skills, but that’s not the case. We actually learn how to socialize as we grow. And like every other learned behavior, some of us become really good at socializing and others do not, just like some of us become really good mathematicians and some of us don’t.
There are, of course, some people who just prefer to be alone more than hanging in social settings all of the time. In general, however, humans are social creatures who are not meant to be isolated. After all, our emotional and physical well-being actually depend on our degree of socialization. You might say that lonely teens who don’t get help overcoming their loneliness often become lonely adults. Regardless, loneliness should be a passing phase. Occasionally though, teens can get stuck in a loneliness rut that seems to last forever.
