First off, let's get you through the next couple days. Wash your hands before eating and after using the restroom, and most importantly, don't touch your face!!! That's how the germs are usually transmitted. Do lots of deep breathing, and tell yourself that you are safe. Tell yourself that over and over and over, even if you don't believe it. If it doesn't work tosay it in your head, write in down (I've gotwhole notebooks at myhouse covered with "I am safe." lol). It will help to calm you down, and get rid of the negative thoughts, at least for a while. Taking a hot bath is always calming for me as well. Try to distract yourself as well. Read a book, or watch a movie that you love.
After this sv attack is over, get into therapy. Find a good counsellor who will listen to what you have to say. Go over to the treatments forum, you'll find lots of good info to print out there to give to your therapist. I've been in therapy for a couple years, and have been working solely on my emetophobia since September. I can't believe how much progress I've made. The most important thing is to do the homework they give you, even when you'd rather play computer games (that's my biggest problem!). I never would have said this a year ago, but there is a way out of this phobia hell....it just takes a lot of hard work.
