In this episode, MysterE discusses obsessive-compulsive disorder (OCD) and shares his personal experience with the disorder. He explains that OCD is characterized by both obsessions (intrusive thoughts) and compulsions (ritual behaviors). MysterE identifies four major categories of obsessions: fear of germs, fear of something bad happening, obsession with symmetry and organization, and obsession with doing good and avoiding evil. He also discusses various compulsions, such as counting, checking, and cleaning. MysterE shares his own rituals, including handwashing and checking locks. He emphasizes that having quirks or rituals is not the same as having OCD and encourages listeners to understand the true nature of the disorder.
