The paradox of agitated depression
We usually think of depression as a state of complete lethargy, and anxiety as a state of high energy. But the nervous system does not always fit neatly into these boxes. It is entirely possible to experience both states at exactly the same time.
Imagine sitting in a car, pressing the gas pedal all the way to the floor, while simultaneously pulling the emergency brake as hard as you can. The engine is roaring, the car is vibrating with trapped energy, but you are not moving an inch. This is what agitated depression feels like in the body. You have the restless, buzzing energy of anxiety, but the profound physical heaviness and lack of motivation characteristic of depression.
Why the body pulls the emergency brake
When you experience chronic stress, your sympathetic nervous system pumps out adrenaline and cortisol to help you fight or flee. But if the stress goes on for too long, and you can neither fight nor flee, the body realizes it is running out of resources. To prevent you from literally working yourself to death, the older, more primitive part of your nervous system (the dorsal vagal complex) steps in and forces a shutdown.
The problem is, the threat hasn't gone away. So the brain is still screaming "Do something! Fix it! Move!" (restlessness), but the body is responding with "We have no energy left. Shut down immediately" (lack of motivation). The result is a maddening sense of wanting to act, but feeling physically incapable of starting.
"Action is movement with intelligence. The world is filled with movement. What the world needs is more conscious movement, more action." — B.K.S. Iyengar, Light on Life
How to untangle the mixed state
When you are in this state, trying to force yourself to be productive usually makes the restlessness worse, because it adds more pressure to an already overwhelmed system. Conversely, trying to force yourself to "just relax" is impossible, because the adrenaline won't let you sit still.
In therapeutic yoga, we approach this mixed state by first addressing the hyperarousal. We use grounding, rhythmic, and repetitive movements to give the restless energy a safe outlet. Once the "gas pedal" eases up, we use supported restorative poses to signal profound safety to the body, allowing the "emergency brake" to finally release so true rest can occur.
