I too have emetophobia and was very concerned about my treatment making me sick. I had both chemo and radiation and tolerated it very well. I did not throw up but was nauseated toward the end of treatment although i think that was probably due to side effects from the chemo. I believe my fear coupled with a strong will and meds helped me through. Did they not offer you chemo? I know I didn't want to go through treatment either but your team will take good care of you and any discomfort will be addressed. If you haven't done so already, let them know of your phobia. But as a fellow phobic, I understand where you are. Hang in there. You can do this.
