Guilt sometimes causes insomnia. The Guilt of being a self perpetuating burden is one possibility.
Like if instead of getting your rest so you can work the next day, you make nonstop posts here and on AVS.
Posts that not only show you know next to nothing about audio/video, but posts that usually contain...
"If I had a job, I would..."
"My parents wont let me...."
"I just can't do..."
"Someday when I have...."
"I would do that, but...."
"Maybe tomorrow, I will....."
The best thing for you would be if your parents shut your phone/internet down.
