Does anyone have intense anxiety mainly in the mind sometimes without physical symptoms?

I feel isolated because everywhere I look people talk about all the physical symptoms which I do get but sometimes I have this intense rumination of thoughts that boil down to an intense feeling of despair. feels like an anxiety attack on the mind. I checked my pulse and it's normal, no chest pains, no breathing issues. It doesn't allow me to do or think about anything. And is there a medical term for it that I'm missing?
