Major fears?

Vertically enclosed spaces, especially if it's dark. I don't know why. That's pretty much the only extreme phobia I have.

I have too many to list.
Dying a slow/painful death
Getting some horrible disease
Death of someone important to me
Losing the ability to have childeren :'(

I have alot more, but those are my top four.

Also, I've always worried about attending a party because I always think someone is going to push me into a pool and I'll drown.
