I am not speaking to you personally, but I think that in general there is a very large trend right now of people who believe they are introverts when really they are suffering an accumulation of social anxiety that life has freed them from the need to work through.

I suspect that for many, if they had less social anxiety, they would actually prefer to socialize more. But the most successful way to reduce an anxiety is through exposure therapy: forcing yourself to do the thing. And in today's world it is much too easy to simply avoid exposing yourself to any socialization.

I see a lot of people who claim to be very introverted. But, also, a lot of those people are unhappy. They may be comfortable, but that's not the same as happy.
