“Just because something is addictive doesn't mean that you will get addicted to it. But . . . if your stomach ties up in knots while you count the seconds waiting for a phone call from that special someone . . . if you hear a loud buzzing in your ears when you see a certain person's car (or one just like it) . . . if your eyes burn when you hear a random love song or see a couple holding hands . . . if you suffer the twin agonies of craving for and withdrawing from a series of unrequited crushes or toxic relationships . . . if you always feel like you're clutching at someone's ankle and dragged across the floor as they try to leave the room . . . welcome to the club.”
