TL;DR of the above for anyone else: Socializing is a muscle which can and should be exercised.

Which I actually wholeheartedly agree with. I had a similar experience to you, though not as extreme. I had maybe one friend, didn’t talk to people, considered myself an introvert, basically the typical person you’re talking about. Then I met someone who taught me how to exercise that muscle, and encouraged me to meet other people. Took some time, but I went from having one friend, to having over a dozen. And I’m capable of actually talking to people I don’t know now, instead of clamming up and getting anxious, most of the time. Barring certain physical or mental disabilities, I always try to encourage my introvert friends to talk to others more, as much as it’s a horribly embarrassing, awkward, and especially draining experience at first.

This all being said, you sound like a douche. Especially with that last paragraph. Chill, my dude. Don’t immediately assume you’re gonna be under attack. There’s hardly enough people on this site to spam you with replies anyways.
