Laughter is said to be the best medicine but not always.
There are situations where you cannot laugh. In tamil there is a saying " when you are in trouble laugh".
One person asked a question "Is it when another person is in trouble?"
This is so to say that if you wait patiently with faith, then other complications can be avoided.
Otherwise one trouble leads to another and it multiplies. Like when you drive with tension you may end up with an accident which may complicate things further. Even otherwise blood pressure or other stress related diseases may get hold of us.
Nothing is in our hands. So leave it to god and wait. There is no other way.
