Hi Bluecharles,
Your mind is overwhelmed and in a state of fight-or-flight. You need to find ways to relax. I would recommend researching breathing techniques, meditation, yoga nidra, prayer, etc. This will calm your body’s stress response, which in turn will calm your thoughts. Eventually, you will need to redefine the thoughts that are leading to your anxiety, but calming the response first will make that less overwhelming.
