I actually have a heavy form of insomnia, I basically do not sleep at all, it doesn't matter what I do physically or emotionally or even if I take pills, I basically stay awake and my brain keeps thinking by itself (especially in the night when i'm very tired it keeps thinking and sometimes it even starts creating melodies)when I'm super tired i might get get about 1/2-1 hour of sleep every week. But yeah, I'm not really having the best life really because I'm tired half of the day and get huge headaches.
I have insomnia, but you sound like you have it much worse. I bought one of these fitbit things and it tells me that I get an average of ~4 hours' sleep a night, and will often be restless 10 or 20 times in that period.
I used to be like that when I was a little kid, but it got worse and worse,
