@Xander94 dude you are better looking than me, and I look like white Chad without the muscles. Quit browsing lookism, quit looking in the mirror so much, and quit adding "cel" to every f*****g word.
Your problem is you are too smart for your own good - your brain obsesses over details in an obsessive compulsive way, and it does this because you don't interact with people. When you spend that much time alone, you start analyzing your own heartbeat and freaking out and worrying over the slightest problem. Sometimes you even create problems so you can worry about them - this is your brain legit f*****g with you. It's f*****g with you because it is so f*****g bored that it needs some stimulation. You need to get out of the house, and not spend so much time on a computer - spend some time outdoors, where the stimulus from your surroundings can entertain your brain to the point where it won't torture you. Your brain is like a dog - keep it inside in a locked apartment and it won't take too long before it rips up your couch and shits on your pillow.
Meanwhile, you'll think "that's not possible, i'd know if it was all in my head" - but i promise you, you wouldn't. That sneaky f*****g brain of yours is so deprived of stimulus that it will fool you into thinking you've caught ebola from the pizza you just microwaved just so it can occupy itself by browsing WebMD for 6 hours.
