How can i improve my life?

Well dude I am a sixteen year old girl and Hell I smoke a little too much also. But hey i feel the same way i have a boyfriend who has just recently moved in with me and my parents. He's older by the way but e-mail me i know how ya feel. love_dahling@yahoo.com. Im always lonely and im a very normaly happy person i dont know why life sucks and I dont know how to make it better. I could use some advice also. It'd be nice to have a friend. even if it is just online.
