Until you realize that your worth is not dependent upon how much better or worse you are (which is totally subjective to the person judging) compared with those around you, you're never going to be happy. There will always be someone smarter, dumber, richer, poorer, more attractive, less attractive. If you keep comparing yourself to him or others you're never going to be happy. You have to find happiness in other things. Find things you truly enjoy and appreciate. Don't look at someone and say "it seems like everyone likes him. I wish I was him" because you never will be him and you don't really know if people like him for the right reasons. Lots of cool/popular people in high school try to let that carry them through the rest of their lives and it doesn't work. Just be happy you're you. No one else can be you. Learn from your life and share that with someone else and make them better. That's way more important than the other things you're putting so much stock into.
