Ni act

In 2017 i had borrowed 100000 rs from a friend in Mumbai, who gave me 90000 rs after deducting interest of 10%. Later I returned him another 15000 in two cash installments. After i lost my job I had asked him for some time to repay and given him a signed cheque. When COVID broke out in the country he started to demand his money back but due to problems i wasn't able to return the money. In 2020 he filed a NI act case on me seeking 230000 rs in a fictitious complaint and bounced the cheque that I had signed and given to him as surety. I have our WhatsApp conversations and call recording that the amount was 90000 and that the complainant filed the complaint under pressure. Actually when i got the notice I had questioned my friend why he put a false case so on that phone call he accepted he made a false complaint under pressure. I took bail in the case and was not able to attend court due to my father's death. Now the next hearing is in January In WhatsApp messages he has threatened me that he has police contacts and is also friends with the MM listening to the case and he also mentioned contacts with goons. I borrowed only 90000 and paid 15000+10000 so only 75000 is due not 230000 Now i have been diagnosed with cancer. Is it possible to deposit the whole 230000 as mentioned in chargesheet to court and ask for exemption? Can I request the court to continue hearing the case because I can prove my innocence. But due to cancer I am not able to travel. Will the court listen to me. Is there a way I could request the court to verify the call recording also to prove my innocence. Please help.
