Lip side are cracked. Something serious?

She is suffering this for more than 6 months now, the side of the lips are getting cracked every now and then. She has taken homeopathy medicine for many months...Under medication the first few months it is getting cured and again it is relapsing. The homeopathy doctor had undergone some tests in the month of November last year 2018. The reports had two or three things out of control : 1. Vldl cholesterol level high 39 mg/dl    (normal - <34mg/dl as per the inference) 2. Triglyceride - 213mg/dl (normal - 60-170 mg/dl) 3. Vitamin D - deficiency 14.5 One more thing to - it has been 1year she has lost her husband and going through mental agony, which she is not expressing out. Can anyone suggest what should I do ? I am very confused whom to go and is this something serious ? Need some guidance on the same.
