This was me. I was 14, my parents just divorced and I got hooked on Starcraft in 1999. I would play until the sun came up, go to school and sleep through class. I did it for 3 years straight, with varying levels of addiction.
At some point, my mom wanted me to see a pyschologist but I tried to show her I wasn't addicted. I took the cd out of the computer, cut it up and glued it to a piece of paper. I hung that paper on the corkboard for all to see, then, not 5 days later I bought another cd and started the cycle again.
I don't know if I was reeling with teenager angst or overloaded emotions because of the divorce but I needed help and my parents didn't know what to do. I nearly didn't finish high school because of it.
Now, with a son of my own - I am constantly thinking about how in the world do I expose my son to technology but also teach him moderation. I don't want to have a fight about how much time is too much, I simply want the technology to be useful to solve a problem and not something my son feels compelled to use all day long.
