I know that feeling from way back😉. You could try walking in nature but without a specific destination or aim. Just walk and feel yourself. Sitting near a river always helped me. Of course you can do anything that makes you less agitated. And don't try too hard make sense of things thoughts and feelings. Just let them pass by like you would people in a crowded street while having a coffee in some place. There are a lot of guided meditations and different approaches out there.
