Oh God  this is the saddest thing I've read today. Perhaps it is helpless when death exists before our eyes that we cannot do anything else. I really do not know anything to help you, praying is not a good thing, it will not help you. Instead, I think it would be better to continue living happily, for example traveling. But in this situation, you can't even travel. Damn virus 
This is the first time I've seen someone with this disease, hopefully you can overcome it to continue living happily
