my son working, his marriage, my work and my two boys very close

I have been praying for the past 18 years for my son to start working, do well his career, my Lord is not listening to me at all. For Dan and his wife are happy together with success marriage. My business is so much down, I don’t know what to do anymore, my two boys are not talking to each other, I cannot take this pressure in my life at age of 75, help me please, I am ready to die and leave this world. Help me with your prayers
