I feel like i don't have a personality?

For the longest time now I feel like i have no personality because i have no friends and even though i can relate to a lot of things people say i can never relate enough to one single person. I can relate to some about one topic but that would be all. I day dream a lot and listen to a lot music. I love arts and sports and hanging out, but not enough of anything it seems. I'm not sure exactly who i am..or where i fit in. Every time i try to communicate with someone it becomes 'awkward' for them, but for me i just keep desperately trying to think of things to try to say to them so they will stick around just a little longer so maybe something could bloom. This happens 2 or 3 times and then things just get so weird to the point where they don't talk to me anymore. Every time i ask my highschool 'friends' what happened? if we used to be closer or better friends or my parents they say its all in my head. have i not been living my life till lately?
