YvonMarie's manga / #sorrow(1)

I've read this back when I was in 5th grade. Probably 2015 I think. Yes, I was in elementary for heaven's sake. It was written on my old journal my grandma gave me which I took out cause idk, I miss her. Blah blah I read this to distract myself from crying but well here I am, bawling my eyes out. I remember I teared up when I read this before but now it hits different. Also how is this connected to the movie (birds don't fly smth I forgot) ? I've heard that movie for who knows how many times know but I still haven't watched it.
