Hey there,

I have had this same issue, and I managed to survive it without getting a *sv. Chances are it's just your anxiety and the stress you're feeling, that's actually making you feel nauseous. I know that when I hear that someone feels sick the knowledge eats away at me, even if I don't realise it, and it makes me feel really ill to the point where I think I've got it. But in reality, its just me stressing out.
You've been doing everything right, washing hands and not letting it get the better of you, so chances are you're absolutely fine. Washing your hands its the best thing you can do, as well as keeping your hands away from your face etc.
You say you have been worrying all week about it, well if you were going to get a *sv you would have had it by now I think. Try to eat, even if its just dried crackers or "safe" foods like that...you will feel worse if you have nothing on your stomach.

What about listening to relaxing music? I recommend Enya personally Other than that I truly hope you get through this tough week ok, I'm sure you will.
Best wishes,
