"When you get exhausted, frustrated, overwhelmed, or run down, your body is saying that you are doing things that are none of your business. God does not require of you what is beyond your ability, what leads you away from God, or what makes you depressed or sad. God wants you to live for others and to live that presence well. Doing so might include suffering, fatigue, and even moments of great physical pain, but none of this must ever pull you away from your deepest calling and God."
