I didn't use to like spiders, but doing an animal management course at college I had to hold a chillian rose turantula (sp) - it wasn't as bad as I thought! My friend hated them... and admitted to being scared, she wouldn't hold it, but she touched it, and said she felt better for doing it. Maybe if you can do something similar?
I actually like Spiders now, although saying that, I still scream if I see one crawling across my living room LOL.
