High "neuroticism" is tendency to ruminate on one's life experiences in a negative way -- to reflect especially on difficult situations and experience anxiety or distress. It is one of the "Big 5" personality traits. It's not the same thing as being crazy or a neurotic in the Freudian sense (which is not a personality trait but a condition or syndrome, more or less vaguely defined).
