im 14 and a girl. when im in cl or just about anywhere i want all eyes on me. i like alot of attention from people. i like it when this dude i like is payin attention to me.i act stupid alot because its fun to me.im sorta loud and crazy and i get in trouble in school for it and my cousin said that i have low self esteem but i dont think i do because i feel really good about myself and i was wondering do i really have low self esteem and is it ok to want to be the center of attention all the time.?
