You'll know the feeling . How you feel insane and time passes so slowly when you're not with them . How they dominate your thoughts and you can almost feel them with you . How you can't help but smile when you know they're thinking about you . How when things aren't going well it drives you insane , and you can't seem to think straight . How when they're not yours , you miss them so much , and you feel that dull emptiness in your chest . Most of all , you'll know how they're literally everything about you , and NOTHING can change that . ♥
