What advice can you give to your readers, who may share something in common with Esther?

Let God who made us the way we are, do what He wants to do with us, to fulfill His own purpose. Interestingly, His own purpose is always the best for us. We may choose to berate God for the circumstances which we have no control over but these circumstances do not limit God.
Let us spend quality time before God to seek His purpose for our lives. It is not the absence of difficulties that brings peace and fulfillment, but the knowledge of who we are.
