Whether you're aware of it or not, you're probably comparing yourself to celebs you see on social. "It is natural—if often unhealthy—for humans to compare themselves to others," says Carla Marie Manly, Ph.D., a clinical psychologist who deals with self-esteem and body image, and author of Joy From Fear. When "perfect" photos of "perfect" celebrities are put on a pedestal as the "ideal" standard, "those who are not able to achieve this truly impossible level of perfection secretly (or not-so-secretly) feel shamed and defective," she explains.
