Emetophobia

As some of you may well know, I suffer from emetophobia.
Emetophobia = Irrational fear or anxiety towards vomit, vomiting, or seeing/hearing others vomit

My fear is so bad that it keeps me from doing things such as, but not limited to (dammit):
-Riding Rollercoasters
-Watching PG13+ movies
-Being near drunk people
-Ingesting food and/or drink that may have the slight possibility of making me sick
-Becoming bulimic (but that's a stupid thing to do, anyway)

Every time I feel as though I may vomit, I go through a episode of panic until either I feel better or I become absolutely positive that I am going to puke.
These situations usually go a little something like this...

...or like this:

But lately, it seems that I am currently unable to vomit, due to my near-crippling fear. You get no details >:C
