Shawn Mendes has felt heartbreak, but nothing quite like what his ex did to him. Blindsided completely, he's left with nothing but pain and his sugary-sweet voice, which he uses to express how crestfallen he is. This is the worst thing in the world, probably, but he knows he'll be okay if he can just accept the fact that you're gone. Still, being alone is pretty hard for him, especially when he needs all this stitching up. My advice? Pick up the needle and thread and learn how to sew yourself up, Shawn. In fact, do it to the infectious beat of this song. You'll be better in no time.
