What's your worst fear?

I have a fear of heights, to include flying in an airplane and standing on the balcony of a tall building.

Losing my best friend.

mmm... having to live without my mum that´s a scary thought! : (

fear of lame forum threads

(KIDDING!!!)

I have a fear of heights too, but not aeroplane just tall buildings when I get too close to the edge...

Death by drowning.

I'm afraid of disappointing the people I care about, and of wasps.

Losing the person I love.

Being alone when I die.

My daughter dying. And sometimes when I'm having really dark thoughts, I imagine my Mum and daughter dying together - now that would really kill me.

I second Keydeck. Nuns. *shudders* scary.
Though snakes are sorta cute...

Being alone whilst I live.

My worst fear is finding myself putting myself in harm's way, for no good reason. I'm sure that's not very healthy, but fortunately it's more like an acting musing than anything like a phobia or real fear.

snakes

big bugs! I shuddered and was on the brink of being inconsolable when I found 7 huge wasps in my room while on a seminar for work. Still gives me the creeps!

A tremendous fear of stamps.

I had an awful nightmare this week that I was stuck on a crumbling ledge of an ancient building very high up and couldn´t get off...the only way off was walking on a very narrow strip of stone to a staircase...luckily I woke up...
