Non-Compliant - Covid 19& Self Quarantine

I am well aware of our nations fight of Covid 19-- Have been self quarantined since March 10th- I have no problem doing this- Unfortunately my 68 yr old retired brother also lives with me-- We are both retired- I never wanted such an arrangement- (long story)

Now we are to follow self quarantine - I am stage II not bad (use an inhaler) once daily-64 now. I realize the gift from China could very well kill me- But I have a brother that is indifferent to it all- He must have soda, chips, snacks, comfort food to feed his Diabetes type II- I made a mask for I knew he would head for the store soon as $$ came- I am riddled with anxiety(take xanex) I do not think I am fit to survive a Ventilator! After 40 min. fighting over this I had no choice! My medications are still not right (have chronic bronchitis) chest aches- I use Breo 100/25, NO rescue inhaler since 2018! Have a Dr. phone appt on the 14th- Can't use Incruse, Trilogy or generic ventilin. My chest aches if I press on it. I know my living arrangement causes more harm to my already multiple health issues and COPD condition. I will have to handle living arrangement after this Pandemic- My question is What to do with others who live with you in this situation, Is anyone else going to the grocery store with a mask on? How are us COPD patients to protect ourselves from the ignorant uncaring family member? I run behind him with the spray bleach cleaner wiping everythng! Tell him to wash hands!! I know this is ridiculous but surely cannot be uncommon- Many of us do not have the most charming arrangement! I ask has anyone had Covid 19 and lived??? I have 14 days or less for signs and the fool will have to go to the store again- Start the cycle all over again! It does not seem lawful- For another to put a COPD patient in harms way- Any suggestions- I even offered to use my credit card for online shopping- I clearly think he has dementia - Any legal idea's or suggestions welcome- I have called my apt manager asking for the price of a one-bedroom - But office is closed - What are we to do? I live in Calif - San Bernardino County- What makes this so upsetting is most Covid 19 cases have no idea where they picked it up!! I'm not even sure if this is the right forum for such a mess-
