Gosh, I'm sorry about your awful night.

My daughter gets chest pains when her anxiety is bad. The only thing that stops that is usually her beta blocker Propranolol. It works on the physical symptoms of anxiety. Doesn't help the reasons why a person gets anxious in the first place.

Lots of people on TBI/PCS get anxiety after their accidents and head injuries too. For people like myself who had anxiety prior to a head injury, life can get very complicated because of the fear of being hurt again. Anyway... long story.

I hope you're able to get some rest today.
take care there Dave.
