What can be the best treatment?

Hi, friend a girl aged 17 is afflicted with some neural or a kind of psychological disorder. That is while writing she feels like somebody holding her hands tight. And she has a lesser sleep at night. It seems to have neural disease and psych disorder too. She feels always that somebody is watching her and reserved. Actually she has no gaming and any other sort of such physical activities. Her dad always used to fight her mom. This also has an impact over her mentality. And she worries about her ill health. But i think she has just a kind of psychic problem. Please tell me what kinda disease it may be and suggest a treatment too........ Do NLP suits this kinda problems?
