Another long night/morning

Okay so i'm having some really bad sleeping problems and i've thought about it and I think it's because i've had alot of stress lately. Pretty much to sum it up me and my boyfriend/bestfriend are having some relationship problems right now, both of my grandpas' healths are bad and getting worse, i'm nervous about college orientation and going to the school, i'm losing my patience and getting extra stressed because of two people who usually stress everybody out but have been worse lately because of some stuff. Does anybody know of any easy and cheap ways or things to help a person relax and fall asleep???
