A pack rat, often referred to as a hoarder, is someone who collects and keeps items that may seem unnecessary or worthless to others. This behavior can stem from various psychological factors, including anxiety or a fear of losing important memories. Pack rats often struggle to discard items, leading to cluttered living spaces. Hoarding can impact daily life, making it difficult to navigate homes or maintain cleanliness. It is recognized as a mental health condition, and treatment may involve therapy and support to help individuals manage their possessions and underlying issues related to their behavior.
