Whenever I used to feel down, I just used to cling on to this verse "Whatever you ask in prayer, believe that you have received it, and it will be yours". I would just keep repeating this verse in my mind when I used to be in distress.

And God has answered my prayers. Now I'm happy and have all the peace of mind I need.

"Praise the Lord my soul all my inmost being,  praise His Holy name; praise the Lord my soul and forget not all His benefits..." (Psalm 103).
