Ponzi Scheme Fraud by friend

I am 21 years old as of today. Between 12/2018 and 06/2019 I have approx 4-5 lacs to one of my friend in greed that he gave me. First he took 15,000 from me and returned 63,000. Then I have him approx 4-5 lacs in greed of similar returns. I took that money from college friends and personal financers. He didn't return 1 rs since then and infact has been threatening me and saying he doesn't have money. I being in 2 ND year of college under 7 lacs rupees of debt have my life ruined. I have a blank cheque from him that I took by chance and all whatsapp chats of us. But I don't have all the call recordings of the time when he use to give me greed of high interest rates. Please guide me with options. I know I did the most stupid thing but he blindfolded me with friendship and made me believe him by making up situations showing his financial strengths which were false. This all happened in Delhi. He was in Delhi from 2016 to 2018 that is when we became best friends but later he went to his hometown in Jaipur. I am still in Delhi. People have ruined my life to extent that I can't live now. I have left my education and now working to repay those people.
