I'm insecure about my appearance but i believe i deal with it better than most. The way i deal with it is i remind myself that I'm not alone everyone has their insecurities which means if i could completely change my appearance it would still create other insecurities, which shows that nothing external could solve this issue. Plus there are millions (if not billions) of people around the world with the same ass problems you face (in my case the way i look) so this shows you're not alone and thats somewhat gratifying to know. So my point is working on you inner self and your state of mind will go a long way in finding everlasting piece. I know its helping me.
