All people have defense mechanisms that cause this. They judge the very things they wish they themselves had the courage to do. It's overwhelmingly natural and very hard to realize in the moment.
You can't get anxiety over missed experiences that you have convinced yourself to despise, I suppose. Too many rejections after trying to make new close friends? I don't need them. Too many rejections trying out for an improv troupe? I don't feel like doing that anymore. Etc, etc the list goes on and on.
