When you feel anxiety or guilt identify the situation and what is truly in your control and what is in others control. (Sometimes writing it down can help bring clarity)
Process what is in your circle of control and look at what you have already done to benefit you or the situation. Also look at what steps you can take to better take care of yourself first and then the situation.
Feel proud of yourself for what you have done or what you have recognized.
Notices what is not in your control and let go of anything you are doing to try and effect or impact those things not in your control.
What boundaries can you set to help protect yourself and take better care of yourself.
Work towards acceptance of situations that are outside of your control.
