advice for girls who barely see their boyfriend

currently in my senior year of high school and my boyfriends a freshman in college and I always have these emotional moments where I get so depressed that everyone around me can be with or see or hug or kiss their boyfriend and girlfriend whenever they want but I have to wait on when I can see my boyfriend again and even though he's only an hour and a half away it's hard, for the girls who deal with even further long distance relationships, how do you guys deal with the emotional times where you just want to be with them soooo bad
