Monday hour one and illness

I became sick over the last week. I have difficulty breathing and fatigue. I had some blood drawn. The doctor said it looks like I have some type of virus, possibly COVID. I’m in a small town in a foreign country, tests aren’t currently readily available unless you’re facing hospital admission. I’m supposed to rest and I have an inhaler. My schedule has kind of gone out the window. I cancelled appointments with clients due to exhaustion, I don’t know how long I will be sick or if I can be tested. I know there are still things I can plan on within my family life, but feel I can’t schedule anything business related where I’ll need to show up. I’m missing a deadline, I’ve upset some people. I’m paranoid about my health suddenly failing. How do I approach scheduling with so much uncertainty?
