Do I have a sleeping disorder?

Iam 17 about to be 18 and lately I just havent been sleepy I think alot of it has to with my knee injury 6 months ago with the a surgery and I havent been able to work out or do CC or anything like I use to basically I just come home play guitar and do my work,I might have a band soon too maybe that will tire me some or maybe I should be worried? its like 4:00am over here and yeah well lol as you can see.

if you need to ask me something you just IM or whatever I dont care

lol weed your a genious arnt you? I ran CC man doctor said once its better I can start going at it again so thats out of the question

You have a stress disorder. It's probably temporary. You need to do constructive problem solving. Worry kills the mind and the future. Problem solving is a good skill to develop. It puts your mind on auto pilot. You won't let your mind rest because you are still looking for the solution. You need to ask yourself, " how can I recover?" "how does my body react to sports injuries?" " how much time do I h\need to find the answers?" "how important is the band to me?" "what is the first priority for my future."

if you have taken out the distractions that keep you up and have done home remedies like drinking a warm glass of milk to give your body tryptophan (sorry for the spelling), you have already tried over the counter sleep aids (take as prescribed) , then i would have your parents to the a doctor to get a sleep study done to see if you have any abnormalities in your sleep pattern when asleep and maybe why you can't fall asleep. then you can get some prescription snooze. good luck man.
