Difficult/impossible divorce

Hello, I am married from 22/23 years. I am a hindu and my wife is sikh. I have a daughter who is 20years old and a son who is 12yo. I was working abroad for first 10 years of my marriage where I visited my family occasionally, However after the birth of my second child I moved to live with my family, Parents, wife and children. There when the problems started. My wife started disputed between my parents and me. To stop this I moved to goa, But the situation became worse, my daughter drifted away from us and my wife started mentally harrasing me. She is a qualified densist. I opened up a clinic for her to practise in goa, But she went behind my back and filed immigration for canada. She did not work in her clinic and partied almost everyday. She only loved to party, drink and be a social butterfly all the time. I soon started getting complains from her patients regarding her taking money from them and not treating them. She threatened one of the patient that she will file case of sexual harrasement if he dsnt let go off the remaining treatment. She started using abusive language. Finally I had to shut down her clinic. Occasionally she used to dissapear to some friends house to stay for any amount of days without informing me. I used to search for her everywhere for days. She only contacted me when her money got over. In 2017 she again dissapeared this time for almost 8 months. I had no clue where she is, eventually i found out where she is. She sent me some divorce papers which i signed. But she did not process them further only to tell me after a year that they were fake. She just wanted to scare me. My wife and my daughter fight all time in the house like cats and dogs. My daughter also has become violent and she even physically harmed me. I want to divorce my wife but she is stalling the process, by not appearing on the date of signing and dissapearing time and again frequently. All she does is screams and shouts and manipulates me and my son in the house. She refuses to find work for herself. She talks non stop till I breakdown. I tried everything to help her build her career, I even worked hard to collect money for her to immigrate to canada last year but her visa got rejected. Now she is applying to another foreign country and I am financing all her ventures as I have no option. I feel helpless and bullied even tough I am the earning member of the house, I have to struggle to get anything processed in the house. She is petty and thin looking lady and I look like a gym going physically strong man, but the kind of mental torchure she does I just cannot handle it. I tried to commit suicide even couple of times, unfortunately I couldnt go through. Now, I really want to divorce her once for all. Kindly help.
