well this sucks.. advice please

just got a new job working with infants which I've done for years now. they require that I have a doctor's note stating I'm physically/ mentally capable of taking care of children in a group setting. well my new doctor doesn't want to write it because I answered their depression/ anxiety questionnaire honestly. (I'm not suicidal just have anxiety and depression lol) I've worked so hard to be open about my struggle with mental illness but I feel like I should start hiding it again so I hopefully can keep doing what I love. 😕 advice?
