When I am wracked with anxiety and trying to force myself a asleep at night
I lie flat on my back and put my hands on the chakra focused on breathing:
( Sacral Chakra Belly Breath Exercise | Balanced Women's Blog ),
(It works on side sleeping too of course as long as hands are on the
yellow/sun chakra)

I use various mantras.


Lately I breathe in and out slowly saying something like this:

"I am safe, loved, and grateful."

Another one is, "I am powerful, strong, and grateful."

Or this: "I have strength, peace, and gratitude.

Some of them are longer.
