Nervous Conditions Ending

The last chapter of Nervous Condition was by far the most intense, that crammed as much stuff as possible within the last few pages of the novel. Nyasha's bulimia/anorexia as a result of her fathers attitude towards her (her father not understanding her and forcing her to eat) came as a huge surprise to me but then again was also hinted at prior to this. It was hinted when she was smoking cigarettes before and that showed how these eating disorders are much more of a Western concept in the sense that many people suffer from these to try and improve their image or because they have emotional problems. Tambu leaving and going to study at the other school was interesting as well. I was surprised that Babamukuru actually beat Tambu for her not going to the wedding because he is not her father and I am also surprised that he did not send her home like he said he would. In addition to Tambu's mom getting married I also found Maiguru leaving very interesting. Her brief time of leave only to come back very quickly shows that she cannot be self sufficient or that she loves Babamukuru too much, but I thought she would never go through with it even it was for such a short period of time. There is not much else to say other then so much happened in these last few chapters of the book and in such a short amount of time it really felt like there was a sense of urgency and tension within the last few pages. Finishing the books makes me wonder what the title of the book really means, what does "Nervous Conditions" mean. Is it referring to the nervous vibes and tense atmosphere given off from the last few pages of the book. Could it be something that happened earlier in the novel, or could the title be addressing a concept as a whole? It is something that I do not fully understand and can only speculate.
