How do you keep your self joyful for longer times?????

Well, as a Christian, I asked God this morning for the gift of joy. I've been depressed for too long. I also look at myself in the mirror in the morning and smile and tell myself I'm happy! I shout out my blessings, and I quote verses from the bible. Like I can do all things thru Christ who strengthens me. I also call someone who's having a very difficult time in life and try to lift them up and while i'm doing that I get joy, because I can hear their mood changing. Its blessing to you to try to help someone else who needs joy.
