Can I file divorce case as I am suffering with schizophrenia

I am suffering from schizophrenia from 2012-13 and I am under medication till now. I was married in 2018 July As I was not interested in marriage with this girl I requested my parents but they didn't listen to me at all and also before the marriage I had requested the girl that I don't want to marry her and please stop the marriage just after few days we had met her and her family (not even two weeks and nor any sort of serious talks had placed between the two families) but she threatened me that she will die and all if marriage is cancelled and I got afraid of this as I was suffering from schizophrenia it made me to remain silent with fear anxiety and depression, but still asked my friend help to this matter and he made a call to her second brother and told him that I am not interested in marriage and I am a mental patient going under medication but even that guy didn't took it seriously. As no one was listening to me without any choice I had to marry her but I couldn't stay with her after one month. As I was getting voices of her that she will die n all and laughing at my situation made my schizophrenia even more worse and every night I was only getting thoughts of killing her so one day I had a big fight in house with my family and I left house. It's been more than one year I didn't speak with her nor my father. As a schizophrenic patient I was not able to concentrate on anything and couldn't get a proper job even though I am Mba from top college. I had been asking her divorce but she is threatening me of death. Only my mom is speaking with me and taking me to medication every now and then. I want to apply for divorce from my side but no one is supporting me nor taking me seriously and I am afraid of her brother as he is a local lawyer with good contacts that he may charge false charges and ask for alimony (as I am jobless from one year and no any source of income apart from my mother pocket money). Now my health conditions are getting worse day by day and making me feel to attempt suicide or kill her and go to jail. So could you please give me some suggestions that how I can file divorce being schizophrenia patient and also not pay for alimony.
