Whenever I hear people relating their symptoms to me, symptoms that correlated with them having v*, I'll usually start to notice those symptoms in everyday life and get freaked out by them. If you were never bothered by those everyday symptoms before, just like if you were never bothered by certain foods before you heard these terrible stories, then obviously the difference is all in your mind.
I've heard it's pretty regular for phobics to have a fascination with incidences of what we fear, and so I understand that you'd read these stories. It might not even be a bad way to desensitize yourself, but first you need to healthy enough to see them therapeutically instead of being scared of them.
Don't start thinking that it's inevitable that you'll be ill someday and let that dread be the focal point of your life. Fact is you might not, I have never had 'it' happen again since I became an emetophobe, about ten years ago. It used to happen every year or so in a pretty regular cycle, and then stopped when I became phobic. I felt unwell all the time due to anxiety, and I was convinced for about a year and a half that there was something physically wrong with me.
I've certainly had plenty of SV's and possibly even FP since then, but the worst that's happened is I've been really scared and had panic episodes at inconvenient times. It's gotten to the point that I fear the panic and stress surrounding the stimuli, more than I do the focus of this panic and stress, because panic is, after all, fear. It's the scary part, the actual thing I fear is something that lots of people go through without much fear, and that isn't a big deal to lots of people.
Lots of people choose to do that which we fear, simply because it eases other symptoms and they've learned it seems to let them recover from illness faster. When you fear it as more than anything else, it becomes quite possible to just not let it happen.
So long as you don\'t give in to the fear, it doesn\'t matter what else happens.
