Was Anna Karenina mentally ill?

[kev67]

Anna does not seem to be behaving very rationally towards the end. She is exasperating. She appears to have lost her perspective. Her emotions are raw and her thoughts are disjointed. She is constantly ascribing feelings and motives to other people when she has no justification for doing so. Is she actually mentally ill? What would a psychiatrist/psychologist (I don't understand the difference) diagnose?

It is a long time ago that I read the book, but I saw a film about it two years ago. She grows desperate. If I remember rightly by assuming her adultery she loses everything she had: her husband, her family (including her children), her friends, her position in society. And she gains nothing because her lover doesn´t want her any more. All doors are closed to her, she doesn´t see any possibility of starting a new life. Quite enough to drive someone mad!

When life seems hard, many abandon healthy habits with unpredictable consequences.
