I was trying to figure out how to explain my BPD thinking to my girlfriend in terms they would understand. I basically explained it as this. Someone shows you a yellow circle and says "this circle is yellow" and you know it's yellow, you see it's yellow, but there's a part of  your brain that's yelling at you, "it's red! it's red! they're lying, it's a red circle!" and no matter how much you try to remember that you know it's yellow, eventually you just see it as red. And no matter what or who reminds you that the circle is yellow, you can't see anything but red because your brain is telling you "red red red". I just wanted opinions on it as this is 100% how things are in terms of my brain.
