I've reached that point again

Every Shuto I've reached this point. The one where I can't stand her and what she does to me anymore and I want to tell her to take a flying leap off a tall building.
I know she knows I'm upset with her. And she honestly can't fix the problem because I can't tell her because I'm not supposed to have feelings.
Everyone else can have pet peeves and breaking points and arguments, but as soon as I step out of line it's game over. Which makes it even more annoying when my emotions rear their ugly head. Because I'm the least allowed to have an opinion but the most likely to need one for all the shit I go through.
