It went so far that when I shelved books at a previous job in a library, I would try to leave the snake books for someone else to put away. Otherwise, I would just hold the books by the binding so I didn't have to touch the disgusting snakes curled up on the cover.
It's normal to be scared of some things, but phobias are irrational fears. Do you have a kind of phobia that haunts you day by day?
If not, you might find some of these fun:
Monophobia: Being alone
Phalacrophobia: Becoming bald
Thanatophobia: Death or dying
Onomatophobia: Names or hearing a certain name
Hippopotomonstrosesquipedaliophobia: Long words
I always thought the names of phobias were intersting. I guess the doctors who came up with them had some fun with it too - the people who have a phobia of long words would be terrified to say what they were diagnosed with!
