Hang in there, Karen!
I've been isolating & only going out for food &, when necessary, home & auto repair / maintenance purchases.
And, I've been in N95s for 2 years.
Personally, I don't pay any attention to the CDC. I watch internatiinal trends & I read Dr Eric Ding's twitter. He is a Harvard epidemioligist & has been WAY ahead of public health agencies &, in my opinion, has been 100% (or nearly so) accurate in his reporting.
This approach has served me well, thus far. For example, when I read about what was happening in China 2 yrs ago, I loaded up on toilet paper & N95s before they were a thing here in the States.
Your life is no less important than those of people who do not have chronic health concerns! 
Dr. Ding's link, if you care to take a look:
