<s>[INST] Hello doctor,  This is a concern regarding my mom, whose mental health has become poor due to sort of negative thoughts after a year ago death of my dad. She is 51 years of age. I can seen her speaking to herself, hitting her head with her hands as something disturbing her brain, and lack of sleep. When asked, she is not expressing it in detail as she feels they are very bad evil thoughts and does not want to disturb us. She is restless even when lying down or sometimes at sleep. Please suggest me on what to do to relieve her from this state and make her happy. [/INST] Dear  The symptoms corresponds to Post Grief Psychological Disorder. But it hadn't subsided for more than a year. Then it is a concern. Self talk, hitting head and lack of sleep - Note the frequency of these symptoms. Get to a psychiatrist with these details. Because this illness should not develop into psychoses. Wish her speedy recovery. </s>
