I never would have expected that from you, of all people. Sorry to hear that.
Oddly, the dark never really frightened me. Funny how all these other things effected me more than darkness is eternal.
It's worse than you think.
I rarely go out when it's dark, because I'm so scared. Doesn't matter if there's crapload of people around or that there are streetlights.
If I stand (not sit) too long in the darkness, I begin to get paranoid. However, if I'm laying on my bed, or sitting on it... the problem almost does not exist.
If I've read/seen something even mildly scary, I will [tornado fang]ing try to lit the lights in whatever room I'm trying to go to immediately. Otherwise I begin to lose my sanity, a'la Amnesia (well not exactly, but you get my point).
In other words:
Yes, people of RPM. Tron is in fact a total wuss who's afraid of the DARKNESS like a little baby.
