Oh so she is stressed cause if Mishaan truth come out then what will happen.. yeah even I felt this is what all about but I felt that it was supposed to be more about leaving Ruhaan since it was shown that she was so deeply felt for him that she even came out of fear of becoming Kunal's daughter by leaving Veer.. I mean her feelings for Ruhaan might have been very deep and now when she is doing all this , she is supposed to feel that heart break no?!.. Isn't this is supposed to be reason for her being not well?!..Of course she has choosen Pari over Ruhaan even then there has to be some conflicting emotions towards Ruhaan , which is missing..
Even I felt it...one sister crying for everything ,another one not crying even after she is going to loose everything
