Incidentally, the Buddha's solution to this problem was to deny desire itself as evil, the cause of all the multitude of evils and suffering in the world. Christians believe that one's desires for good things are ultimately part of one's deepest desire for God; the righteousness or sin comes about in how we act on our desires.
I myself have quite a few worry dialogues going on at any given time. At the root of them, I think, is one big worry that I'll forget something important. But recently, I've come to realize I'm free of one particular burden: the fear of being single. It just doesn't bother me anymore. Praise the Lord.
