Defeating Depression

I struggle with the purpose of depression and anxiety in my life. I have heard many times that it makes you more compassionate and understanding of others. There are times, however, I feel resentment, anger, and frustration. 

I bought the book Defeating Depression, by Leslie Vernick in July of 2010. I started and restarted this book many times over the years. I finally finished it last winter. 

These are two of many passages that really resonated with me.

'But if you've prayed and listened and obeyed as best you can but still feel the heaviness of depression engulfing you, you must learn to cling to the assurance that there are other purposes at work beyond what you can see right now.' 
            Defeating Depression, pg 219-220 (emphasis mine)

'May you come to cherish the secret treasures God gives you during your darkest times.'
