We are human beings and there are a lot which are beyond our imagination and control. Luck is not same for all as it varies from person to person. You will see a lot of people going abroad and earning a lot but there are still the other part who goes abroad and loose everything. I do understand your situation but I can not agree to the fact that you left your parents in the hands of almighty as it was your responsibility to look after them and keep them happy at least in the last days of their life and they were not blessed atleast to kiss their grand children from their only son, you.
