I Have An Unnatural Fear of Garden Slugs

I am literally terrified of these creatures, they remind me of leeches which are another phobia. I'm not really sure when it came about really, I remember one time when I was still in infancy I was at a caravan with my parents and brother and my mother innocently pointed out that it was standing on a slug, when I lifted my foot, I revealed the largest most ferocious blackest ugliest slug I had ever seen in my life! From then on it just got worse. Those damned things were everywhere! I'm not sure when it got to the point of screaming and trembling foolishly whenever I saw one, but it is currently at that point. I know they're harmless but...

PS Fear of slugs is called Limaxaphobia.
