1.) Heights - I am clumsy and fall easily this one should be obvious for me.
2.) Death - Not so much the ceasing to exist but rather what if I have a long painful death sort of thing
3.) Getting caught - Whenever I'm doing something that someone wouldn't like (an authority figure) I fear getting caught because I could and that would be bad
4.) Mayo - EWWWWWWWWWWW... this is sooo gross it scares me. Also, when I was little I had to have it on my hair for headlice it was aweful
