What happens when “I want to look better” turns into “I need to change my body at any cost”? In Part 2, we get into muscle dysmorphia, sometimes called “bigorexia,” and the disturbing ways body image obsession can push people toward increasingly extreme attempts to change their appearance. We explore why someone can be visibly muscular and still feel painfully inadequate, how the pursuit of an ideal body can become compulsive, and what happens when people take cosmetic procedures into their own hands with DIY surgery. Because when the problem is how your brain sees your body, changing the body doesn't always fix the problem.

Everyone has something they don't like about their appearance, but when does insecurity become body dysmorphic disorder (BDD)? In Part 1, we explore how BDD differs from ordinary insecurity, why it is classified as an obsessive-compulsive and related disorder, and what neuroscience reveals about the way the BDD brain processes faces, visual details, and information about appearance. This isn't simply about vanity or low self-esteem, it's about an obsessive cycle of perception, attention, and distress that can make a perceived flaw feel overwhelmingly real.

This week and last, we're diving into Dissociative Identity Disorder—the psychology behind "multiple personalities," why the name changed, the truth behind famous cases like Sybil and Billy Milligan, and what modern science actually says about one of the most misunderstood disorders in psychiatry. As always, it's strange, fascinating... and unsettling.
