Hi Pink Princess and welcome!
I am sorry that you are going through this at the moment...I have a phobia about this to some degree...it is not the actual act that bothers me...it is the weak and out of control feeling...and being so sick with the stomach bug that gets me.
Have you sought any help for this? I usually recommend seeking therapy when some form of anxiety keeps you from doing the things that you want and need to do in life...in other words, if it really affects your quality of life.
Phobias are very treatable. You can ask your doctor for a referral to a therapist who can help you reduce your emetophobia.
Here is a website that you also might find helpful.:)
Keep posting with us...we understand and are here to listen.:)
