A few days ago, I was chatting with a friend for a very long time one afternoon. She wasn't in a good state because of family issues and had been taking antidepressants for a while, which had strong side effects. She also drank traditional Chinese medicine, but it was too bitter to stick with. I was reading "Mental Health Lecture Notes," and it happened to mention depression and anxiety. Depression is when the energy flow in the entire body and mind is blocked, with the spirit, consciousness, psychology, and Qi and blood all stuck at a low point.
