My son working, his marriage, myself and my boys

Nothing is going right with my life, I am anxious, worried, depressed inside, I have been praying for the past 18 years for my son to start working, do well in his career, nothing is happening. Please pray that he and his wife are happy together with prosperity and a successful marriage. My doctor told me I have issues with my heart now, pray nothing is wrong. My work is so much down, I don’t know what to do. My two boys are not close and it’s killing me inside.
I am 74 years and cannot take all this pressure in my life, help me please, I am begging
