My wife has a hysterical tendency

I have been trying to find a remedy for my wife. She has a hysterical tendency that when she becomes upset or vexed a number of mental symptoms appear. She will become completely withdrawn and indifferent to everything even her own little baby, which would be lying next to her screaming for a feed and she would lie still and ignore her cries. She will not speak or eat anything; she will weep and become indifferent to everything. She may get something into her head which would be far from the truth and torment herself thinking about it until she becomes nearly insane. If I try to speak with her she will become quarrelsome, aggressive and blurt out things with the intention of hurting and she will want to torment herself. There is always that sadness in the back of her mind and she speaks very fondly about her dear father who died in a car accident when she was 10 or 11. She told me that at the time it was a huge shock and loss to her and I feel the symptoms she suffers from now could be because of this grief.

When she was in the state I have mentioned above I gave her a single dose of Ignatia 200 which almost instantly returned her to normality. The next time she went into this state I gave her Ignatia 1M which had the same positive result. But unfortunately the symptoms return sooner or later. Shall I give her Ignatia 10M?
