sorry this happened to you...talk about a loser of a cashier. i have the same problem with leaving home and having to interact with people at times. the grocery store especially. they ask how i am doing, expecting fine and you, and i usual say "LOVELY" in a sarcastic syrupy tone of voice that usually stops them dead in their tracks and shuts them up. they dont know how to take it and i get out of there asap with my transaction. probably not the most healthy way to handle the situation but thats how i feel some days and i wear it on my sleeve too. other days are literally fine. i hate rude people and would make a point of making a scene with the manager if this happened to me-but we are all different. its great that you have a supportive husband. i hope you feel better soon.
