Go to phobialist.com and look through the list and see what fear or fears you have!
I have Musophobia (fear of mice), used to have Novercaphobia (fear of stepmom, lol, no joke either), obesophobia (fear of gaining weight), and slightly Omphalophobia (fear of belly buttons, i can't touch mine or someone elses! lol).
That's just a short list of the fears I have, but the "major" ones from the list.
What are your fears?
