Letting go of control, that's actually when you're safe.
On a piece of paper, write down the thing that is stressing you, the obstacle that is in your way. Then put it in a box and just leave it there. At the end of about a week, dispose of it - throw it in the trash or bury it - some sort of ritualistic act of releasing it.
If you're living your life avoiding stress, you must be living on an ashram.
I think quite often we hold onto trauma because we don't process it.
Let go of what you think you need & what you really need will show up.
Much of our anxiety and stress comes when we're focused on fear and disconnected from the voice of our inner guide.
