When the storm is strong, even the strongest of trees lose limbs. The branches that are cracked and spent give way in the wind, yet the trunk remains rooted and most of the branches do more than survive. They are cleansed.
So it is with many things in life. The turmoil comes and the limbs are tested. Some fall away while others remain and become even stronger for the testing. Over time, new growth may rise in the gap created by what fell away.
