A mere 4 hours a day hardly constitutes an addiction. If I lived on my own, I envisage that I would be mindlessly online for 8-10 hours each day. Ironically, I derive little satisfaction from being in front of a screen all the time, but when one has no friends, no job and no real passion in anything, there isn't much else to do.
I keep reading that those on the spectrum have unique talents and interests, yet I curiously do not. I cannot draw. I cannot write. Although reading was once enjoyable for me, my comprehension is atrocious and I have quite literally no imagination at all, thus it seems like a pointless activity. Video games haven't interested me since adolescence. My television is seldom used because I don't honestly care about events that are unfolding in today's world, and I find most of the popular TV shows to be either pretentious or excessively CGI'd. The enchanting thought of being strapped up in a straitjacket in the confines of a padded room grows more appealing with each passing day.
