Thanks for the reply and detailed information.
Well, since you mention that her such behaviour has been there from the time of her teenage years , it seems like that she has Borderline Personality Disorder
(BPD) , also called as Emotionally unstable personality.
People with BPD , have mood instability , are emotionally weak and labile , are soft targets of other people and are prone to Depression. The fact that she goes into depression during her periods which is a cyclical depression and stems from her boderline personality , as she is succeptible to depression and more so the demanding lifestyle makes her all stressed and when she cannot cope with the demands , her stress
overwhelmes her and the depression sets in , which has taken a cyclical pattern , meanining that it coincides with her periods and subsides on its own after a brief period.
I am mentioning below a link to Borderline personality disorder , which will throw more light on it , help you to understand it better.http://en.wikipedia.org/wiki/Borderline_personality_disorder
Now as far as solution to her long standing problem is concerned , i am mentioning below a regime that she can follow and this will help her in alleviating her symptoms.
1) She needs to be evaluated by a psychiatrist for Borderline personality disorder ( BPD) , which has not ben done previously in her case.
2) After the evaluation is complete and her diagnosis of BPD is established , she needs to be started on Psychotherapy , that is counseling in lay terms. Some good psychotherapies used in treatment of BPD are -- Behaviour therapy , Cognitive behaviour therapy , Cognitive psychotherapy , schema therapy , etc . The psychiatrist will be choosing one or a combination of the psychotherapies to manage her Bodrerline personality .
3) Anti depressants such as Effexor XR or Paxil or Zoloft , shall be used for a few weeks to few months to treat her cycical depression once for and all.
So, i suggest you get your daughter meet a psychiatrist , get her evaluated for BPD , and then discuss the above mentioned regime with the psychiatrist and get her started on it. I am quite sure this will help.
I wish your daughter all the best.
