When you are mad, mad like this, you don't know it. Reality is what you see. When what you see shifts, departing from anyone else's reality, it's still reality to you.
I get absolutely shitfaced. I am shitfaced and hyper and ten years old. I am having the time of my life.
Because I'm not, in fact, depressed, Prozac makes me manic and numb - one of the reasons I slice my arm in the first place is that I'm coked to the gills on something utterly wrong for what I have.
