So I had read this before, but the dementors, to whom we are first introduced to in Prisoner of Azkaban, are clearly symbols for major depressive disorder (depression). The description of the effect that dementors have is what people who experience major depressive episodes feel. They feel like they’ll never be happy again. People with depression often also experience anxiety, as anxiety disorders and depression are commonly comorbid, and we see that with Harry to an extent. The thought of dementors make him very anxious and he is desperate for a solution. In comes the Patronus Charm! Patronus charms are very difficult to perform in the presence of a dementor because they require happy thoughts, which the dementor is sucking away from its victim. This seems symbolic of how difficult is for people who are diagnosed with major depression to fight their way out of.
Here’s a little more etymology for you and it’s from Latin again, yay! Expecto Patronum = I await a protector. The Patronus is the protector! Did I mention J.K. Rowling was a classics major? She was.
