Symptoms of body dysmorphic disorder

Some symptoms are that you believe people are mocking you and how you look in negative ways, you tend to try to hide your "flaws" with makeup and cloths, comparing yourself to others, always seeking approvement from others, perfectionist tendencies, avoiding social situations, etc. 

Hope that helped:)
