Why do I get huge bags under my eyes & I'm only 14?

I am 14 & I seem to always get these ugly bags under my eyes for some strange reason...I cant say their perminent but I always get them...I know its wrong to stay up all night & get no sleep but even when I do sleep alot I still see bags under my eyes...Can I get rid of them or if I dont get any sleep they will stay there? helppp????? I feel so ugly right now :-(
