Sumi, pls read my earlier post.......ur wife seems to be Bipolar ( BPD - Bipolar Personality disorder) Sumptoms - extreme behaviour traits OR frequent mood swings. At one stage u will find them very happy while on the next minute they will be very sad and may even talk about their life being ruined/hopeless.
There was a need to go to Psychiatrist and hence u took her there but to a wrong Psychiatrist ,who seems to have chatted or counselled ur wife and then suggested some TIPS. There are expert Psychiatrist who do not treat a patient unless they administer a Personality TEST like say MCMI Test (Millon Clinical Multiaxial Inventory) .Its used for diagnostic screening or clinical assessment of adults who evidence problematic emotional and interpersonal symptoms or who are undergoing professional psychotherapy or a psychodiagnostic evaluation. This test will tell you where the problem lies in behaviour of person on parameters like say Anger, Anxiety, Depression, Narcisstic , jealousy, initiative, focus, etc etc
Ur wife seems to have high apetite for s*x than normal people do and thats cause of her irritation when her needs are not fulfilled. She likes to be pampered like a princess and would not like to hear the word "NO" for her needs and desires ( correct me if im wrong)
Im not asking you to go for divorce and im sorry im saying few things about a lady who happens to be ur wife but please try to address the real issues and take steps . All the Best !!
