I forgot that this talk existed! It was such a strength to me on my mission. It's called "The Great and Wonderful Love" by Elder Anthony D. Perkins--it's all about recognizing Heavenly Father's love for us, despite our weaknesses. Here are some quotes from it.

"Consider three examples of how Lucifer is 'laying traps and snares to catch the holy ones of God.'...The snare of false inadequacy....The snare of exaggerated imperfection...The snare of needless guilt."

"God the Father is merciful and has infinite love for you despite your faults. Only the voice of Satan will cause you to feel of no value. In contrast, the Holy Ghost will cause you to feel 'godly sorrow' 10 unto repentance in a manner that fills you with hope of positive change."

"Doubt, fear, and worry indicate we have taken all of life’s burdens and anxieties on ourselves."

"You will experience greater joy in life as you eradicate adult-onset pessimism and substitute childlike optimism. Optimism is a virtue that allows us to see God’s loving hand in the details of our life."
