“Anhedonia” is the psychiatric term for the inability to derive pleasure from things that are normally pleasurable. It’s the characterizing symptom in major depressive disorder, but it can also be a symptom of substance abuse, schizophrenia, Parkinson’s disease. I learned the term in a university lecture hall and immediately felt a shock of recognition. Anhedonia was the feeling of “nothing,” the thing that kept my mother in her bed.
