Thorn,

Fear, when stripped right down to the most basic level, is of the unknown that lies ahead of you.

Fear of...being alone
Fear of...being divorced
Fear of...failure
Fear of...disapproval
Fear of...Koosh balls...

I mean...fear is all in your head. It is not the type of fear that is fight or fight type of response when confronted with danger.

Fear is not knowing the exact outcome and that drives people nuts sometimes. So in order to 'see' some specific outcome of a situation we are not sure of/about, we exert control of the situation by manipulating people and/or the environment IN ORDER to reassure ourselves of the pre-conceived outcome that we want to see happening.
