The place became desolate after me, or when else would I have found rest?

This powerful couplet speaks to the profound loneliness that follows a significant departure. Mir Taqi Mir suggests that once he is gone, life becomes desolate. The second line implies that only his presence provided the comfort and peace (sleep) needed to endure the world. It's a poignant reflection on being the sole source of solace for another person.
