Being in a state of indifference, or not caring one away or another.

For instance; lacking passion, motivation and desire, possibly due to emotional supression- leading to one becoming apathetic about their situation.

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.

A complete lack of emotion or motivation, whether directed towards a person, activity, or object.

While it can often be confused with Stoicism, apathy is much worse than merely not showing feelings, as the person who is apathetic HAS no feelings.

I don't really feel like writing a definition..
