Read this book for absolutely no reason

To my friend who quit

Why did you say absolutely nothing, I really cared about you and it broke me to see that you didn't say a single word to me, even if I'm the slightest chance you might see this, please come back, I miss you and your positivity, sure, you had rough patches such as them, but you still made it through, so can you come back or atleast tell me a goodbye like you left me with nothing.
