Insomnia

So for basically as long as i can remember i have the worst time going to sleep at night. It never was really a problem id stay up all night go to bed at like 2 or 3 some night almost 5 or 6 but get up atleast by 9 or 10. Now that i am living with my mom it has been tough. I never want to be in the living room and the best time to watch tv or shows on my computer is through out the night. Lately though it has affected my days i sleep all day because either it is i do not want to be in the living room with the family or i should say mom whos always nagging or im just really too tired. I dont know what it is i feel like it is just the whole nagging becuase in my own home i would get up and do stuff and not worry about anything. Ahh i dont know what i want to do either, should i take sleeping pills and try and get sleep even though when i actually do go to sleep early i still sleep in or figure out a drive or way to get up and out of bed early. I am going to start trying a few different things. Ill post on here if changes in my life take affect and work... let me know any input or advice id appreciate it.
