Superman wasn’t affected by kryptonite and neither are you. It’s what the kryptonite represents: the root cause. For him, it meant he was torn from his world and his family. And since he never dealt with it, the emotion associated was his weakness. So you see, there never really was a kryptonite. It was all in your head. Think about that next time someone says everyone has their kryptonite! Or anything that you feel took you out of your power. It’s your choice to allow this or not.
