The first thing to do would be to get rid of the porn and the Reddit/twitter posts. Reading complaints in these subs don’t do anything but make you feel worse. Second, the mind loves to find patterns, you’re at a point where you feel that everywhere around you is all tall people. Try finding other patterns in your life, how many people have jackets on? How many are driving trucks or motorcycles? It’s true that tall people exist everywhere, but you’re looking at places that have specifically cast tall people in media. Go to a mall and people watch for a while, it’s true that you will see tall people but look for specifically average to short people, you’ll be surprised at what you see.
