Hi Majda , 
That’s a perfect analysis thanks for sharing , I just wanted to add that her knee osteoarthritis was a self worth conflict as you mentioned because she was dreaming of another bright life and she failed to fulfill her ambitions by these two unfair marriages , she felt that she doesn’t deserve that and it seems that she was regenerating but her regeneration symptoms were aggravated with her brother and mother loss , she felt Isolated I guess ( and you can confirm that with her ) because it seems that her brother was supporting her in this painful journey and she lost that support by his death , 
All what she’ve been through formed her personality and this is a cerebral cortex constellation that brought this bipolar disorder to her personality, because she was torn between two personalities through her life , the ambitious girl who loves life and has lots of dreams and the oppressed one who was obligated to marry an elderly man who buried all her dreams , which later formed her personality disorder ! Triggered by the memory of her brother’s death date where she remembers his support to her dreaming little girl personality and reminds her on how he rescued her from that oppressed little young girl married to that elderly man !
Thanks for sharing this Majda ! It was brilliant!
