Credit Card bill non-payment due to financial trouble

I wish to seek legal advise on this matter. Please guide. Last year (Year 2018) around July, I had lost my credit card (which I ultimately got blocked as well). Around the same time I also lost my job. The situation thereafter has been dismal and I am struggling to make my ends meet for the last 9 months now, trying hard with the support of my family to take care of the expenses and the responsibilities of my life. Even, though i have a good education background, with enough experience but with changing market trends its not easy to find a job and that has been the case since I lost my last job. After loosing the credit card, I tried making payments (in parts) over the next few months, but could not pay the entire amount as there have been responsibilities that have eaten up any buffer money which I had. Currently I am in a bad shape, trying to pull myself up but still with no money to pay the dues, which have amounted now due to late payment charges and bank interest which has accumulated. The bank has handed it to the recovery guys, who are calling countless times, threatening legal course and harassing, which is making things worse. I want to see an advise as to what is the best thing I can do to resolve this. Thank you gentlemen.
