It's nasty virus. I had it last year and I don't want it again, so I know how you're feeling. I think treating it as a bad case of flu. Rest, staying hydrated and eating even small nourishing snacks if you can't face eating a meal, is the way to get through this. Obviously if you feel it's worse than that, or you have difficulty breathing then you need medical attention.
I fainted a couple of times then read that it's one of the symptoms.
Hope you have help to get in meds and provisions etc. Treat yourself with care and it does get better. Not right away, but day by day and you will get through this.
