Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. The mood swings and anger could be out of disappointment about her health condition and the task in front of her. Disappointment which arises out of unforeseen life events do bring such symptoms like sadness, irritation, anger, lethargy, lack of interest, lack of appetite etc. Please understand this fact and make sure to introspect. Talking to her friends, out door activities and being creative should give her relief. Find the reason for her disappointment and consult a psychologist if need be. Psychotherapy techniques should suit your requirement. If you require more of my help in this aspect, Please post a direct question to me in this URL. http://goo.gl/aYW2pR.
