Kotaku: When it was reported that Eric Harris and Dylan Klebold, the perpetrators of the Columbine High School massacre were big fans of Doom, the original first person shooter in the eyes of many, I dismissed the idea that violent video games could have been responsible for inspiring the event. As a lifelong devotee of video games, I thought that idea was ridiculous.
That was back in 1999 when I was in my early 20s. It was also the year when I was diagnosed with bipolar disorder. It's impossible to pinpoint precisely when the illness began, but mood disorders often kick in with the onset of puberty. My parents sent me to my first therapist when I was 15 years old, so that sounds about right. It also means that I'd coincidentally been suffering from bipolar disorder for about 15 years before I sought treatment.
