My wife is not happy in talking with anyone even with her family like her mom, dad, sister, bro and so for me. She normally irritates when we talk to her. She usually sleep and watches tv during the entire day. Earlier she was very energetic all the day. Now she doesn't bother for anyone from the last 15 days. Before that she feels happy and sometime she feels sad but when we ask that what is making her sad then she said that nothing and also not disclosing with anyone. We got married since end feb 2017. And I was observing little bit this behaviour from last 2 months. She was is at her mom home from last 1 month for preparing her xams and now she is not talking to anyone and normally irritates when we talk or touch her. Please suggest me what should I do she was very caring and helpful to others but now her behaviour has changer rapidly. Which doctor should I go to either neurology or a psychiatrist. please suggest me asap.
