"I was in a car accident a week ago. I crashed into someone after passing out."

That's genuinely scary. On the one hand, your T's concern that you not become afraid of driving has some validity. On the other, your T is not (I suppose) a medical doctor. Diagnosis or lack of diagnosis permitting, you may still need a supported return to driving. I personally can appreciate your concern to cause no harm to others (I no longer drive).

Wishing you well, Nicoleb2
