Lithium is for depressed people who are already listless. Anxiety medications douse the fiery urge to be active, and compartmentalize the potential energy that is not converted into kinetic energy. Unused potential energy manifests as antsyness; which compounds to be depression.

Over time, low-energy leads to low activity and poor fitness. It is a self-feeding problem. The lithium makes you content to do nothing. With it, your anxieties and urges are at a complete standstill and you can tolerate the boring blob you see in the mirror.

Without it, you see the Dorian Gray you have become.
