Wrongful harassment and fir

My marriage was held in December 2020. My age was 37+. ..and my wife is around about 6 months elder to me. During covid time we had a very small marriage. Marriage was fixed with the help of a mediator(who is invisible nowdays) My wife left the house in July 2021. 30 weeks of our marriage, 9 weeks she spent in her parents home for holiday and all. I have not taken any dowry ..and neither my parents have taken. Both my parents are cancer patients, my father had his 2nd operation just before marriage and third operation happened in November 2022. My wife has filed a false fir case...saying I have taken dowry worth 30million rupees, physical and mental abuse by me and my parents. They are using the local police to harass me on a regular basis. The girl has taken back with her 90% of things given by my family in wedding...and 99% of things she had got. Even after that they are demanding the above said amount, harassing my bed ridden cancer parents... I had filed a sec9 thing before she had filed her fir... but it was a waste. The girl and her family are producing false black money given as dowry reports and other papers. Police is asking me to prove I have not taken the dowry, I don't know how to prove but I had submitted 5 yrs of my and my parents financial bank reports and all.( obviously nothing there, cause I have not taken anything) The girl wasn't married for so long because of n number of health problems...which they hadn't shared before marriage. They were looking for a goat to cut the head and eat the mutton...and they found my family.(my bad luck/karma) There main intention is money...even if that means mentally killing my 2 cancer patients parents... or sell my every body part for money. My father already has wasted much of money remaining with us on lawyers( sorry to say but max lawyers don't care about justice....but only money) I wake up everyday with the wish to end my life...cause of police harassment. I can't even die cause my parents don't have much age to live. Someone help me... I will sell my kidney to pay your fees if it comes to that.
