Self inflicted insomnia

[Oralee]

Also know as [SII]. Self Inflicted Insomnia is a basic lack of sleep caused by your own boredom and lack of interest in sleep. People with Self Inflicted Insomnia could sleep if they so desired, but they dont care to, so they [stay up] as long as possible, sometimes [for days].
A person with SII doesnt necessarily need a reason to stay up. Usually people with this disorder spend their time on the internet, even if there is nothing to do. Theyd rather stare at [a wall] than close their eyes.
