Also, have you tried journaling?. Just write how you feel and what you are feeling. It can help you burn off the self worrying thoughts.

It takes a time for the CBT coping mechanisms to work. Keep doing it.

Any time you feel anxiety about getting hit on the head or almost getting hit . pay attention to what you are feeling.

The sensations you are experiencing. So you maybe sweating, breathing rapidly, mind racing etc.. And then tell yourself: your in a safe place.

Lastly, breath.. Take some breaths. Do this everyday and I can tell you your body will deal with anxiety in a better way. Also, do something to take your mind off these episodes. Talk to a friend, watch a sitcom. Something calming and fun that suits you.

* remember it takes a significant blow to get a concussion..
