Unable to pay the Personal loan EMI - Lost the job and huge amount from capital market

Hello all, Thanks for providing the free legal advises here. I am from hyderabad and borrowed a Personal loan from ICICI bank for 3 lakhs rupees. the loan was purely processed depending on my salary income and financial history. Unfortunately i have lost almost 5 lakhs net amount in capital market (share market), thats my biggest mistake that i have invested the amount in capital market which i borrowed from Bank as a personal loan. still i was able to make EMI for some months and later due to some other internal issues i was forced to leave from company. now i have no source of income at the same time i am not finding any suitable jobs to recover from my financial crisis. This information was given to the bank that i need some time to repay the loan emi's as i have no income. but bank is not ready to give me the time and harassing me for repayment. this loan was taken without my family knowledge, my family members are not aware that i have borrowed a loan and also lost the amount in capital market.... how can i manage this situation please advice. Spending sleepless nights with the bank calls and feeling panic to handle them. some times feeling to go for suicide as i have no option left.
