Certainly Yin Yoga can help you: one of the lovely things about yoga is its ability to affect us and help us on so many levels - physically (hopefully you have already discovered these benefits); mentally (which we will talk about); and energetically (which you have noticed.)
Yin Yoga provided periods for mini-meditation which can allow us a chance to train the brain, improve concentration, help deal with anxiety disorders. There is a section in YinSights that you may find interesting: it is called
A.W.A.K.E.N.. By being aware, first of sensations in the body, which are plentiful in a yin class, and then of thoughts in the mind, we can begin to allow the thoughts to go. First you have to be aware of them and then the practice is allowing - allowing them to go: not forcing them to go and not hiding from them either. We allow unhelpful thoughts to go like we allow our out breath to go.
This practice is not simply introspection: that can be unhelpful as well, when it lacks intention and direction. This is a directed investigation of what is actually happening, making a deliberate conscious choice and changing your mental state. This is simple; not easy; but very effective when practiced regularly; when practiced with both attention and intention.
Energetically we are dealing with the Sympathetic and the Parasympathetic Nervous Systems. I have written about how beneficial Yin Yoga can be and how to increase the "rest and digest" function through simple breath work in this newsletter
article. Try these simple exercises and see if they affect the degree of agitated energy you have been experiencing. You can also try this at other times in life when things get a little crazy or stressful.
I hope this helps.
