You are not suffering from a chemical imbalance in your brain. You are suffering from a social and spiritual imbalance in how we live. Much more than you’ve been told up to now, it’s not serotonin; it’s society. It’s not your brain; it’s your pain. Your biology can make your distress worse, for sure. But it’s not the cause. It’s not the driver. It’s not the place to look for the main explanation, or the main solution.
