Anyone get ask cant you just get over it?

I was speaking to a family member the other day and I was talking about my anxiety and how I have anxiety and how sometimes it's bad like crying and panic attack. She then said "I dont know how you have anxiety about anything cant you just get over it." I tried to explain to her that no I cant and she looked confused and upset like anxiety was something you could turn off and just choose not to feel instead of feeling like a train hit you in the chest.
