It's simple. You're more intelligent and open minded than those who down you could ever hope to be. The fact that you want to be your own person rather than mindlessly conforming to what the norm wants and the fact that you can actually think for yourself makes you special and above many people especially at your age. Don't let anybody tell you otherwise.

You're amazing and will most likely do great things in life.

If those you call your "friends" don't appreciate you, find people who do. Open minded intellectuals such as us have trouble making friends because it is rare to find like-minded people when you're part of a subset of people that is comprised of less than 3% of humanity, but that means that the friends we have are all the more special.

Keep your chin up, don't let others drag you down to your level, and continue to want to learn, grow, and improve yourself and you will be fine
