I don't think you're surrounded by people who are smarter than you. I think you're surrounded by people with more experience than you, and bigger egos, and warped personalities. The personality issues make them feel the need to make you feel less than them, so that they feel better about themselves. If they're smarter about anything, it's how to manipulate your emotions.

You either need to learn to ignore the emotional manipulation, or you need to get out of that toxic environment. And you need to hold your head up. Learn what you can, but don't learn the attitude. It will ruin you.
