The artist is entitled to his/her peculiarities in writing, as dark heart suggests, I feel sure.

Dr. Kay Jamison Redfield has written about the fact that many artists (who comprise a much higher percentage of bipolar patients than the average population--about 20%) must have an experience of trauma, or melancholia, or depression--whatever one wants to call it--that drives the creative spark in some writers.

Joyce Carol Oates declines to accept that view and believes that calmness and
quietness are the keys for writing (as well as the giftedness, of course).

I believe in both: even in the sensitivity that writers have to beauty, and I think that is a strong drive for creativity. In fact, I think that a significant number of bipolar patients are
gifted in some field, whether it's art, writing, architecture, engineering, or whatever.

Whatever suits if it works!
