A fight is mental, not just physical and psychological warfare is absolutely part of that.

I’m nuts, baby, I’m mad. The craziest friend that you’ve ever had. You think I’m psycho, you think I’m gone. Tell the psychiatrist something is wrong. Over the bend, entirely bonkers. You like me best when I’m off my rocker. Tell you a secret, I’m not alarmed. So what if I’m crazy? The best people are crazy!
