Eclipse was the most painful for me to read.
I became a fan RIGHT before New Moon came out... and I organized my reading schedule so that I was able to read Twilight, then watch the movie, then go see New Moon, then go home and read it. Truthfully that was the best way for me to do it. My BFF had already read all four books and she knew I would have a mini-break down reading NM... so she told me to watch it first. Two hours of misery is a lot shorter than reading 600+ pages of misery, ya know?
So I knew how NM ended and I was excited to get to that point. With Eclipse, I had NO clue and I have never cried so much during a book in my life. When Bella kissed Jacob... I remember dropping the book and re-inacting (although had I the choice, I wouldn't have) Bella's nightmarish cries and screams from NM the movie. You know that screaming and trashing about? Yeah, that. I was literally hyperventalating. Mind you, I had done NOTHING, literally, for the past four days or so, I woke up and read and forgot to eat and read... the books consumed my very existance until I finished BD. I had all the books next to me so when I finished one, I didn't even take a breather or bathroom break before beginning the next one. And then she kissed Jacob and realized her feelings for him. I was SO heartbroken. I am NOT looking forward to seeing that on-screen.
It was bad enough that during my shower between NM and Eclipse, I started bawling because I so desperately, at that moment, NEEDED Bella to be with Edward as much as they needed to be together. It was unnerving. I walked around in Bella's depression the entire time. I was "in" her head and conversley, she was in mine and I couldn't separate her sorrow from my own.
I REALLY want to see Eclipse on screen but I am terrified of how I'll react in front of people....
