Hi dear, I can understand you emotional disturbance, during your period time as there will be hormonal imbalance naturally most of them feel low, sad, anger, frustrated and other things. This feeling will come by quarrelling or fighting with others. For a moment we ourselves wil feel the reason for this behaviour. But introspect yourself is there any other disturbance in your life which might also trigger that time. Its better you visit psychologist to handle your feelings and over come the disturbance if any.take care
