Health spreads further than the body. There is the health of your sleep, your finances, the friendship you have been letting go quiet for reasons you would struggle to explain.
These systems talk to each other constantly. A money worry becomes a shoulder. A conversation you keep dodging turns into a stomach. The body keeps a very literal set of books.
If one area is doing badly right now, it is worth asking whether the symptom and the cause are even in the same department. Often the fastest way to feel better physically is to handle something that has nothing to do with the body.
