Words don't trigger me anymore (except when I'm feeling sick or having a panic attack) but I used to be so severe that when I was 6 years old, I would scream at anyone who said the word, "throw up".
You are emetophobic if:
1. You have an intense fear of vomiting or nausea or other people vomiting and it has lasted for more than 6 months.
2. If it affects your daily life and prevents you from doing stuff.
3. If you consider vomit your worst fear and you'd rather have anything else happen to you.
4. You have panic attacks when you are about to vomit or someone else is about to or has vomited.
5. You have a very hard time controlling your anxiety about it.

I have some time periods where I'm so petrified of vomit that I can't leave the house and I panic a lot. Then other time periods where I still need medication to stabilize myself but I can still live and have fun without worrying about it constantly and I only panic like a few times a year. Right now I'm going through another hard time where I'm depressed and I am so scared I can't leave the house and barely even talk to people or eat.
