Dude. It's fucking not. I mean, sometimes it is. And maybe I speak for myself on this one but even when I am my most irrational, I almost always KNOW I am being irrational. I just can't control my emotions in hyper-drive and need a hot second, like you pushed the button or whatever on the Millennium Falcon but forgot you're approaching a yellow light at an intersection. Maybe my speed is wildly inappropriate, but depression hasn't eaten away so much of my brain that everything I say should be less credible than that of others.
