The authoritative term psychotic depression makes Kate Gompert feel especially lonely. Specifically the psychotic part. Think of it this way. Two people are screaming in pain. One of them is being tortured with electric current. The other is not. The screamer who’s being tortured with electric current is not psychotic: her screams are circumstantially appropriate. The screaming person who’s not being tortured, however, is psychotic, since the outside parties making the diagnoses can see no electrodes or measurable amperage.
