Answer:
hoarding disorder
Step-by-step explanation:
DSM-5 contains descriptions, symptoms, and other criteria for diagnosing mental disorders. In the scenario being described, it seems that David meets the hoarding disorder criteria. This criterion is defined as an individual with the following symptoms:
- Excessively acquiring items that are not needed or for which there's no space.
- Persistent difficulty throwing out or parting with your things, regardless of actual value.
- Feeling a need to save these items, and being upset by the thought of discarding them.
David meets all of these symptoms by not wanting to throw away anything in his house.
