Hey

You have nothing to be ashamed of. There are more people out there afraid of foods than you think.
I am glad you got to get it out and talk about it and probably "flooding" is a good idea because I don't know if there would be any simple steps to this or not,maybe putting a little on your finger at times and just having to hold it there?
Could you try remembering in your mind what the lady said to you.....and then say you might think its disgusting but it's good!!!!!!!
People eat all kinds of weird things, and your hotdog and mayo isn't that weird at all.
I love fried potatos and eggs with vinegar poured on them....YUMMY! My hubsand could puke when I eat it. LOL...But he eats pickled eggs and I think thats gross

But anyway.....could you have wanted approval from this woman so much that by her saying that made it turn into this fear?
Just wondering
Take Care
