You don't need help, you need to read the EO and learn.
EO 63, Section D, Item 6, Paragraphs 1 & 2.
>6. Persons with health conditions that prohibit wearing a face covering. Nothing in this Order shall require the use of a face covering by any person for whom doing so would be contrary to his or her health or safety because of a medical condition.
>Any person who declines to wear a face covering because of a medical condition shall not be required to produce or carry medical documentation verifying the stated condition nor shall the person be required to identify the precise underlying medical condition.
You do not have to wear a mask. Your medical condition is healthy and oxygenated, wearing the mask is a threat to your health due increased intake of CO2 and forced recycling of any expelled germs that might have entered your system. It does not say affliction, it says condition. Plus, due to HIPAA you do not have to disclose your medical condition, which again is healthy.
