Cant Sleep

Well for some reason i cant sleep tonight i don't know maybe it is because i keep thinking about what everyone is saying about me, Maybe it is because i don't think i have any real friends. Ok me and my "friends" hang out but only when it suits them never when they just want to hang out with me. I don't get it maybe i ant that fun or maybe it is the wrong kind of people.......The only problem is there the only kind of people i know......Maybe i need to reach out to other kinds of people...I don't know what kind of people would except me though. I am the kind of girl that drinks smokes and loves to have fun but when u cant have fun by your self.   What do i do? and, Who am i really?
