The gratuity is not enough to cover the loan. What to do?

I am 58 years old working in Abu Dhabi. I am terminated from my work due to redundancy. I have a bank loan and my end-of-service benefit is not enough to cover my loan balance.

Is it possible for my gratuity to cover my monthly payment to the bank until such time I could find another job?

Are bank loans covered by insurance?

If I could not find a job and I cannot pay my loan balance, will I go to jail?

Please advise on how to settle my loan with the bank.
