I'm not sure what to do

My dad wanted me to eat chipolte knowing I have a life threatening IGE >100 milk allergy. My dad thinks that I need to face my fears and live my life without being afraid of my allergies. I feel like he is wrong since I've been to the ER multiple times because of my allergy and he has seen them touch cheese when handling food. I'm not sure if I should listen to him or not since it is concerning my saftey. Idk what to do I need advice.
