As a fangirl, they're are plenty of ways to die. For your sake, I'll list four (ahem, TOBIAS)

#1 Drown in tears reading TFIOS or other sad books

#2 forget to sleep because you're too busy reading (sleep? What the hell is that?!)

#3 hyperventilate and pass out after seeing a picture of your OTPs

#4 explode of feels
