I remember when I made my first post here - straight after pressing post I went for a walk - wow I was scared, and I could not sit still.
Back then while I was exiting I wasn't really thinking of the consequences beyond myself - it's a shock isn't it. It was a vulnerable time as the person who I thought was the Lord of the Universe turned out to be a greedy businessman. Turns your world upside down doesn't it, and for a while cleansing your soul is what matters most.
I tend to think of the fear I experienced as one of those things - like sunshine makes shadows, living a lie creates a fear of disclosure - it builds up subconsciously, and it packs a punch when it flies.
Motives are another thing of course.
