If you are feeling down try not to listen to sad songs.
Satan can use music for negativity.He also can make you feel sad.So if anytime a sad song comes on.Or a bad influence song does you can turn it to another song that is not.You can listen to Christian music it takes you remind off of things.To focus on our Lord.That will please him by listening to worship music and worshiping God.
If you sometimes wants to listen to decent classical  or smooth jazz music you can.Even piano ones or not piano ones.Listenimg to sermons on the radio,online or on Youtube can do.Talk to God it can be through prayers and closing your eyes.And you can also talk to him without  closing your eyes.He is with you wherever you go.
