Look man. I have some pretty crippling social anxiety and PTSD. So do a lot of other people. The point is, you've gotta get to a point where you don't let it rule your life, or define you. Every day is a battle but it gets easier and easier when you remember that everyone is dealing with shit. Everyone. That includes the most boneheaded people who don't understand what it's like to dread the house inspector coming over, and just spend the days leading up to it dreading it, even though it's just a simple thing. I've been, and still continue to be somewhat, so anxiety ridden that I don't go downstairs in my apartment building to check my mail because I don't want to speak to people. I go at night, when there's nobody there.

Just, like, don't make assumptions about people, cause you never know what they've been through or what their day-to-day is like. Cause we're all just people. And life is a shitshow for all of us. Even "Chad" who seems so oblivious and happy, he ain't that happy. He's got shit going on too. Nobody is any better than anyone else. Keep that in mind. We are all in our own personal hell.

Edit: I know reddit has a boner for this guy and I'm not trying to feed the circlejerk, but Louis CK had a great episode that sort of pertains to this. It was an episode of Louie called "Cop Story" and Michael Rapaport played a typical numbskull, hard headed cop, but then some things happened (no spoilers) and you got to see that he was just a dude trying to navigate the world like the rest of us. One of my favorite episodes of the series, and Michael Rapaport was fucking amazing. Seriously if his performance doesn't make you tear up a little, we can't ever be friends.
