DEAR HARRIETTE: Lately, my anxiety has been keeping me up at night, scaring me away from windows, crowded places, public transportation and tall buildings, and causing excessive overthinking. With recent developments between the United States and countries like Iran, I am afraid all the time. Social media doesn’t help by simply mocking all this serious political unrest with memes joking about World War III. It makes everything feel more chaotic and unpredictable.
