When do you know?

When you know you don't wanna give up, You hold on tighter. When you don't wanna give up, You wonder if what you're going through is worth it. When you don't wanna give up, You become blind. When you don't wanna give up, You have a hard time letting go. When you don't wanna give up, It hurts when someone tells you that you need something better. When you don't wanna give up, You realize you have everything you want even if it's not good for you.
