True friends are a sure refuge

"In poverty and other misfortunes of life, true friends are a
sure refuge. The young they keep out of mischief; to the old
they are a comfort and aid in their weakness, and those in the
prime of life they incite to noble deeds."

-- Aristotle



It's true that you will find out if who are your true and real friends during difficult times and hour of troubles. Some will ignore you, but there are also others who will lift you up during your down moments. It is also during difficult times that you will discover if who among your friends are matured and ready enough to face difficult situation with you, and it is also sad to find out that some of your most treasured friend are the one who will deny you in your most down moments.
But that is life, take it.
