Same. It can be very hard to deal with at times. I've had to take breaks in-between at certain points in order to help myself cope (which is rare for me). I'd skip it if it weren't for the fact that I'm a completionist & don't want to miss any of the gallery events. & it's hard to know when exactly the dark stuff is going to rear its head since the game tells you if it happens, but not when it happens.
I am doing the dark route first so I can enjoy the good route all the more without having to worry about what's to come at the end of the journey so to speak.
