Help with a luck spell?

I would suggest that what you need is neither a spell or a prayer. You need self confidence and self affirmation. Every day when you wake up say to yourself "today is going to be better and I can make it happen" (and try to mean it and believe it). Say the same thing to yourself as often as you think of it. Eventually you will begin to make the choices that make the day better. Your attitude will attract what we call good luck.
