Read John 16:33.

Pray the following:

Thank the Lord for this promise. There is help is learning that what you experience isn’t uncommon or unexpected.
Express your troubles to the Lord. What disturbs you right now, big or small? Cast those anxieties on the Lord because He cares for you.
Ask God for help entrusting those to Him.
Thank God for Jesus, who experienced trouble. We can take heart because we have One that has gone before us.
Thank God that Jesus has overcome the world, and that, in Christ, we too will overcome the world.
