It would be a toss up between fear of heights (acrophobia) or small places (claustrophobia) because I fear them both equally...
I have emetophobia, so that would have to be my top fear, however I am scared of the future, the unknown and death... Pretty grim stuff, really, but there you have it.
My worst fear is fire cuz I've had a fire not long ago and since that day I hate fire
Albeit we all perish one day, my worst fear is simply disappearing from this Earth. I fear what comes after this life, whatever is next... I fear the unknown, like what lays beyond the observable Universe, perhaps even within its bounds! It's so scary to think about, and my greatest fear of all. (That, and someone knowing all my little secrets! :o ...)
My fear is flying, heights , falling
Heights that include free falling, such as when you jump off of something and you have a harness attached to someone below and you free fall for a little bit. Also roller coasters are really super scary to me. I go on them anyways, but I scream because I'm scared not because I'm having fun.
Other fears include snakes, wasps, and pain.
Loud noises. Even when I was little I didn't like loud noises that and anxiety.
People... I'm not joking. I am terrified when I'm around people.
To fail.
