My phobia is called Emetophobia. Its a fear of vomit. Ive had it for a long time, but since ive had kids its become alot worse.. to a point i was getting anxiety attacks every day when DS would cough or moan the wrong way.. just with the thoughts he would be sick.. even though i knew there was nothing wrong with it, its just a mess and id dealt with it before.
I ended up seeing my doctor as i was living with this on a daily basis. She put me on Lexapro and oh my life hasnt been better. I dont think about it like that anymore.. and when i do i dont get hot sweats and my heart doesnt race. I feel like im normal again.

So maybe if its really effecting you that much, having a word about it to your doctor might be an idea?

Best of luck.
