Let it go.
Stop holding on when the one in your grasp clearly wanted to be free. The longer you hold on, the greater the one wring for its freedom. The tighter you clench, the more painful you have to endure - both for you and them. Learn to let go. Let go for your own sake and peace. Because, oh honey, if it was any good for you, it should have stayed.
Be grateful for what you have because:
"And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe.' " [14:7]
