Almost nothing, but maybe a tiny help... in a big bowl of water, add I tiny bit of colouring at a time. The slower you add it, the more your mind can adjust..... Have something safe with you, whatever makes you feel safe.

Same with all fears, you get used to it one little bit at the time.

Hmm.. I might have this. I'm not scared of blood but I get a sick feeling and want to vomit when I imagine blood. Literally only when I imagine it - I can see it in real life, mine or others' blood, in video games, in drawings and I feel fine. But if I read a book that describes blood or think about it or hear a story about it I feel nauseous. Anyone else have the same?
