Harrassed and Tortured - Taken a loan from Loan Apps from Playstore

I had taken small loans from loan apps that are available in playstore at a much higher rate (around 40%) of interest and that too they deduct the interest and disburse the amount.its a short term loan for 7 days. I did it out of desperation, as I'm unemployed and was in need of money and for critical medical emergency needs. Initially i repaid the amount, when they call one day in advance and say that there is some server issue at their end and asked me pay one day in advance. I did it. Again i took a loan from them and when they said the same story of server issue and asked me to pay one day in advance, i asked them you already charge high interest and why did u ask me to pay in one day advance as well. Then they started to blackmail, harrass and threaten that they would send nasty message to my known contacts and spoil my reputation, fell prey into their harrasment, searched for similar apps in playstore, borrowed from that and paid them. And this continued for every repayment where in ended up borrowing from nearly 20 apps. The total borrowing would be less than a lac on all apps put together and most borrowing were due to the harrassment to repay the previous one. While repaying in various apps, i could able to realise that many apps had a same payment upi and realised that it was same person posing as different app individuals. And these upi Ids keep changing daily or even hourly I requested them time to repay as i thought to put a full stop.to indefinite borrowing from such apps so.that i can repay as I'm unemployed and into much deeper life Threatening medical emergency for which also I'm unable to take care. But they are not paying heed to my request. They also charge hefty daily interest which is unimaginable. I realised that i had got into a bigger trap and now the harrassment and torture had gone so bad that they started pushing filthy messages to my contacts and also blackmailing and harrasing me almost through out the day Few PPL send out whatsapp msgs like, u r aadhar card will be sold to drug dealers, says they will tetm me as rapist etc Pls advise how to go about and handle
