Jenny Han said this quote

I could feel my insides sink. My knees too. So I sat on the ground, against the wall, letting it support me. I thought I knew what heartbreak felt like. I thought heartbreak was me, standing alone at the prom. That was nothing. This, this was heartbreak. The pain in your chest, the ache behind your eyes. The knowing that things will never be the same again. It’s all relative, I suppose. You think you know love, you think you know real pain, but you don’t. You don’t know anything.
