End of Nervous Conditions

This reading was definitely the most heavily annotated sections of the novel. Line after line shocked or intrigued me. I was surprised at the amount of unanswered questions I was left with at the end.
What exactly happened with Maiguru when she left? She came back an entirely different person. Was this because of something that happened while she was gone, or did Babamukuru talk some "sense" into her when he went to retrieve her? Is this new found personality fake, like a cover up of how she really feels? It does not seem realistic that she could become an entirely different person in just a couple of days. This makes me think that it is artificial, just a show to put on, possibly for the health of Nyasha.
Is Maiguru's return disheartening to Nyasha? As Maiguru was leaving, Nyasha said "now she's broken out, I know it's possible, I can wait." This leads me to believe that Maiguru's return was actually unhealthy for Nyasha because it only reinforced those walls that she feels trapped by. That idea of no escape could have been what pushed her further into anorexia or bulimia.
I thought it was interesting that on one page, Tambu spoke of how she could not even dream of forgetting where she came from, her family, and friends, even if she wanted to. Then not three pages later, she has suddenly run out of time so that there "was none left in which to miss Nyasha, or my uncle and aunt; and if I had ever really missed my home, I had long since stopped doing that during my stay with Babamukuru."
Does Tambu not realize at all that Nyasha is crying for help, or does she just choose to ignore it? She receives many long letters from her frequently, one even speaking of her "diet to 'discipline [her] body and occupy [her] mind." I can't imagine that she could have received all of these letters without having the slightest idea of something going wrong. And she didn't even write back, so the letters stopped. I think that the point that the letters stopped was kind of the point of no return. Nyashsa had then lost the last friend that she could turn to, succumbing to her illness.
