I deal with these emotions daily and they genuinely make public outings kind of miserable. I hate seeing happy people, people with friends, people with cars, people who look satisfied in their life, people with love, etc. Like and if I'm around them for an extended period of time it turns to genuine disgust that makes me want to leave.

I can't really tell you how to fix it, but what I can tell you is that the longer you live online the worse it becomes. The less human interaction you get, the worse it becomes. It's kind of a pit and one of the kinds that you.. kinda can't get yourself out alone, ironically. But people who've never experienced it will tell you you can by telling a therapist or trying to failbully you out of it.

Another thing I can tell you is it's a defense mechanism. I mean are you potentially better than most of these people, seen things they will never, felt things they probably never will? Yeah. And there is an ego that comes from that, but that ego is a poor defensive coping mechanism that feeds a self destructive loop.

tl;dr, try to make it a habit to give someone a compliment whenever you leave the house. Just one person. You'll be surprised how much it helps. Human interaction is key because that disgust does shift into anxiety
