is a pretty strong statement. Six months probably seems like forever but in the TBI/PCS world it's really not that long a time.

As others mentioned it does sound like you need to be medically evaluated. You have some symptoms that are relatively common with PCS, but your anxiety isn't helping. I'd see a neurologist, after that a physiatrist visit might be helpful to develop a therapy strategy.

Worry and ruminating on your anxiety isn't helpful. Developing a recovery plan with professional guidance will be.

Best to you as you recover.
