Our bodies work in a complex interconnection of various chemicals. To keep in good condition, our body works hard to keep chemical reserves and usage in an ideal “good zone” and does some on the fly compensation if your levels are just a bit out. If our levels are far out, we become unwell in some fairly predictable ways which we call Mental Illness. When we understand what our Neruotransmitters do and why their level is important is to understand the Goldilocks Zone and Mental Illness, and why this turns psychology and psychiatry on its heads.
