Harassed by wife

Hi, I have been married for 6.5 years. There are feuds almost everyday at my home. My wife demands money from me and keep on threatening me to insult me in public and calling police wherever there is a heated conversation . After few days of my marriage I got to know about her mental health for which she was on daily medication and there are lot of mood swings happens due to that. I have been trying to settle and stay happily with her for so many years but there are regular fights happening . I am now scared that when she keeps on threatening me for calling police and dials 100 and call advocate sometimes. Her parents have not been supportive at all and she also abused them on phone. We stay in bangalore as a nuclear family and no one interferes in her life. She is not ready to manage the house , taking care of our only daughter as well. I got her admitted in an online MBA course as well as per her interest and wish but now she has left that course as well and I have wasted a big amount of money as fees as well. I am unable to understand what should I do in this case.
