You are more likely either prone towards nocturnal activity - a "nightowl", if you will - or else you have a serious case of insomnia. I hate having insomnia but I love being awake at night. I just can't be awake at night because I have to be awake during the day so I have to take sleeping pills.
Humans naturally don't sleep 8 to 10 hours at time. We're actually supposed to sleep 2-3 hours at a time for 3-5 times a day. These periods are the times in which we're the most tired. Of course this may not completely relate to you if you have insomnia but if you'd like to learn more search: Rem Sleep
If you're in your teens it's not unusual to need more sleep and/or for your sleep pattern to be disrupted. You could try "sleep hygiene" and see if it works. Let more light into your room in the morning or be outdoors, sunlight helps reset your clock. Stay away from doing things that activate your mind before bed and go to bed just a little bit earlier than usual gradually working up to getting earlier over a few weeks.
They tell you not to nap but napping for 1/2 an hour around mid morning/lunch helped me, if I tried to get up early and push through the whole day I'd end up not sleeping for days then crashing and sleeping for 14 hours, usually because I'd gotten some bug from being exhausted.
There's a condition called "day night reversal" which can be from a disruption to the sleep pattern, from an illness or a sleep disorder in itself. The treatment methods don't work for everyone but if you can get on top of it you'll be less tired in general and won't have to deal with being a night person in a day world.
Heard about a study that confirmed that some of us are just built that way. Nothing is wrong, we are just different. Been that way all my life. Just don't waste time trying to sleep. Listen to your body when possible. If not sleepy, don't stay in bed. Only if we can sleep when sleepy?
