Seeking Strength in Sadness

Feelings of frustration and discouragement oft times weigh heavily upon all of us, and so it likewise sometimes happens with me.
The best remedy for these ailments, in my experience, is profound personal prayer and Scripture study, albeit, our Savior also has counseled us that some challenges require much more effort: "And he said unto them, This kind can come forth by nothing, but by prayer AND fasting." (From Mark 9:29, emphasis added)
And so it also has been with me.
