Discouragement
- Ask God for peace
- Listen to uplifting music
- Prayer
- Meditate on the Word of God
I can say that I have done all of these at one point in my life to lift myself out of discouragement.
Paul had a method of keeping discouragement away - recalling how God's mercy had given him the hope of resurrection with Christ and the ministry with which he served (2 Corinthians 4).
Everyone needs a strategy to get out of discouragement. I hope some of the above can help you.
