Damn, this is hard. It's easy to hate someone when they are always being a bitch, but when they do their best to help you, even at the cost of their own health, it's hard to hate them. But the pressure keeps rising and rising and the balloon eventually pops.
Some drop everything and saw, fuck I don't care anymore, some run away, either from their house or from the world itself. I have a friend who almost took the latter route
So while you might not hate their guts, you won't really like them and will feel conflicted. You hate the pain they caused you, but you feel like an ungrateful person, because they gave you all they could, as missguided and hurtful as it was.
