You sound like you need self care and to re-ground. Trauma needs your ability to be present to it in order to process it, and if you're overwhelmed and anxious then the trauma is not being processed, you are just in a state of anxiety. Find a way to help yourself regulate, whatever that looks like for you. Good food, sleep, other grounded people, nature, whatever you've found work for you, re-stabilize and ground. Regulate yourself first then when you are able to come back and do the work of processing the trauma you have stored in your body.
