So why the title of this post? Because researching norovirus is not going to help you with your emetophobia. In fact, it may only make it worse. If you are emetophobic you probably think your biggest problem is avoiding or preventing vomiting. But that's not true. In fact, vomiting isn't any problem at all. It's not dangerous. It's not harmful. It can't hurt you in any way. Your biggest problem is anxiety or the fact that you fear something that can't hurt you.
Focusing on norovirus and ways to avoid or prevent vomiting is what will make your phobia even worse. It will trick you into believing that vomiting is some sort of big scary monster to be avoided at all costs. But norovirus isn't Ebola or AIDS - it's a harmless virus that makes you feel quite lousy for 24 hours and then you're fine.
I understand how scared emetophobics are of norovirus - I used to be that scared. Luckily for me, I was emetophobic before there was an internet. I really think that if I had researched all this stuff and gone online talking to other emetophobics my life would have been completely destroyed.
Spend your energy researching ways to get over anxiety disorders. There's lots of that on the internet! There are relaxation recordings, tips for panic attacks, and of course lists of therapists in your area that deal with anxiety disorders and phobias.
