One afternoon a few months ago, I was running errands when something strange suddenly happened in my body. I couldn’t pinpoint exactly what had changed, but a “gut feeling” told me that something was drastically wrong. I tried to analyze the problem but insight eluded me.
Waking the next morning, I felt very sad. Tears filled my eyes. I didn’t want to get out of bed, and couldn’t get excited about things I normally enjoyed. As a physician, I recognized these mood changes as early signs of clinical depression.
