Our emotions for the most part are our choice. We can choose to believe the promises of God and push for them. His Word says in His presence is Joy everlasting, the Joy of the Lord is our strength, a gift of the Holy Spirit is Joy. I believe if you Choose Joy and refuse depression, anger, hopelessness & negative feeling , then Joy will eventually become a lifestyle and be found in some measure in every situation as you pursue God's way .
Here's a great song to stir up Joy, even though it doesn't mention the Lord by name, that is who I sing & dance it to as I cry out for the "fire back in my bones" to be restored.
