What is fear and why do we have it? Does it protect or hinder us in what we do?

Fear, apparently we need not fear anything or anyone but its an awful feeling I have realised.

Its wierd, there was a guy following me ome from the post box. I thought I imagined it then he shouted towards me, I did not turn right away but speeded up getting back home. It felt like he was running behind me but I don’t know for sure if he was.

I felt fearful/scared – What would he do? Is he still there? are there more people? Wy me? Its a strange feeling. One I don’t wish upon anyone.

It makes you cringe inside.
