Serious Medical Condition Question

Hello,

I am in the process of applying for a China Tourist Visa. I am trying to figure out do I need to put yes for serious medical condition. I suffer from bi-polar and anxiety, I am on medications and have been well controlled since 2007. I am afraid of being denied? I know if I put no, they will see the medications in customs when entering PRC. Am I wasting my time even applying?
