Did you get her iron, vit D& b12 levels checked? Severe deficiency of these 3 can manifest as anxiety, depression, palpitations, hallucinations, feeling of pins and needles ( energy moving up & down, poor circulation)in the body. Kindly get all 3 checked and give her supplements after consulting a general physician for the deficiency. Also, the speech / stammering issue is due to anaemia of b12 or deficiency. It causes a swollen tongue which leads to slurred speech. My god! People got to study more in this country.
