You'll know the feeling,

If you've ever been in love,

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 no longer 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 to you, and there's nothing you can do to ever change that.
