I like the use of different names for different fears and the ending.

Good thing the poor girl isn't afraid of big words.

Also okay pantophobia is NOT fear of pants. Got it.

I really liked this. It's so creepy, but yet so interesting. She actually became a phobia? That's so cool!

Wow. This was intense. Fear personified as tiny demons, and then the girl becoming one of them. VERY well written.
I'm...I'm a little afraid now, to be honest. ;)
