Sleepless

I don't know why but I just couldn't sleep early. Is that a bad thing? Am I suffering from insomnia? I could only sleep early when I'm sick that's because I'm weak and the medication which makes me drowsy. I wonder if anything can help me cure this. Ya people would tell me to take sleeping pills. Sometimes I wonder is it because there are too many things on my mind or is it because I'm just like that. I feel that as though it is a bad habit and I'm used to it. I'm worried about this. Apart from falling sick, going to school or having so many assignments to complete will make me very tired. That's when I would be able to sleep peacefully. If let's say I never go to school and I'm always at home, I tend to sleep very late. When I try to close my eyes and forced myself to sleep, it's just so hard. Sometimes I end up crying. I know this won't get any better since I can't control it. Well maybe I just have to do something else to make me tired and head off to bed =)
