Almost everyone has closets full of stuff, favorite mementos, and expanding collections of books or shoes or spices or hotel shampoos. But sometimes our emotional attachments to stuff can spiral out of control, and people become not just pack rats but compulsive hoarders. Dr. Robin Zasio, therapist who specializes in treating hoarding and other anxiety-related disorders, explains what compulsive hoarding is and how to treat it. She’ll also give advice about how to live a less-cluttered, better-organized life. She’s the author of The Hoarder in You: How to Live a Happier, Healthier, Uncluttered Life.
