Being in a hospital going through something like what you did, and surrounded by sick people, is pure torture for someone with emetophobia. But, YOU DID IT! You got through it, and you didn't vomit, even though you did retch. And I know how awful retching is (to me it's the same as vomiting), but you got through THAT too. Try to focus on everything that went RIGHT instead of all the scary things, and know that as each day passes you'll get better until this traumatic experience is just a memory.

Try to keep your mind busy, off of yourself as much as possible. Remember - distraction is our friend!

Hang in there. It'll get better.
