Going Internal 

Going Internal is a term used primarily by the United States Marine Corps to define what happens to an individual when they are completely overwhelmed by the negative external and internal factors affecting them. They are unable to think about anything except for how terrible their situation is. Individuals suffering from this psychological phenomenon usually go quiet for long periods of time and stare vacantly at whatever is in front of them. It is hard to engage in conversation with someone who has gone internal, and when it is possible to get them to talk they usually only talk about how bad they believe their situation to be.

Marine 1: "Whats wrong with Lance Corporal Pyle? He hasn't said a word in over an hour, and he's just staring at the ground."
Marine 2: "He's going internal. He just found out he has 24 hour duty this weekend."
