My wife is very healthy and normal but suddenly she gets angry or emotionally disturbed and try to show her anger by doing extreme things like throwing mobile phone , hitting on her head ,cry a lot ... After some time she will become normal and realise she did wrong thing. I m worried about this , thinking she might take extreme steps when she gets angry. She gets angry for small reason ,which I have explained her not to take things so seriously. What should I do ? How to overcome this,we have a small kid
