Insecurity about facial features: listener question

As I move forward in the world of dating. More and more insecurities pop up about my appearance. Sometimes I feel ok, other times I become hyperfocused on parts of my face that I want to change. Ok, it this is a constant narrative that gets louder or goes quiet for a while. I definitely feel like there is dysmorphia not so much with the body. This has been around from about the age of 12. I know it has nothing to do with me. I have sat with the feelings, know the theory, know I can not secure my identity by feeling attractive, however when something big in my life comes up it is very loud!
