It's hard to be happy knowing you will never accomplish your dreams

So many people say stop worrying about society and just focus on yourself, but it just hurts when yourself is rejected by the world. In high school, I never got to play sports. I couldn't pass tryouts. I still wonder all the memories I could have made from practices, games, and so on. I wonder what pride I could have felt earning a varsity letter.

And I experienced rejection many times in adulthood. In college, I got rejected from the engineering clubs like rocketry and DBF. I got rejected from the fraternities. I got disqualified from the military due to health issues. It sucks I am basically forced to have a basic life due to my own failings.
