This is very tragic, but somewhat understandable. Moments where great change are required can give birth to a new person but sadly in these cases it led tragedy. These moments for he greatest growth in personality development are a 2 edged sword they can lead to growth or suicide.

The Theory of Positive Disintegration is a novel approach to personality development. The theory is a forerunner of what today is called post-traumatic growth. Dąbrowski described the psychological factors he believed to be related to positive (growth full) outcomes after crises. He called these factors developmental potential and they include a description of psychological sensitivity he called overexcitability (OE). Dąbrowski observed that individuals with strong OE experience crises in a stronger, deeper and more personal manner. The intense experience of crises creates an opportunity for the conscious and volitional rearrangement of the self including a reformulation and reprioritization of one's values and beliefs. The individual forms a new image of his or her ideal personality. With this ideal as a guide, the lower aspects of the self are inhibited and higher goals and aspirations emphasized. The theory is a testimony to Kazimierz Dąbrowski's deep insights into human character and development.
