Journaling might be a great outlet for you then. It would be a way for you to "collect" your worries in one place and see them in a tangible light.
Sometimes worries tend to grow in our minds to catastrophic proportions because we let them fester like an infected wound. We take the road of "ignore them and they'll go away", when actually it works the other way around. An unfaced worry tends to grow in our mind until it becomes a fear or even a phobia. Yours are trying to break out through your dreams.
By writing out your worries you can look at them and see that they are manageable - or at least some of them are.
I wrote an article on fear that I think might be of some help, (If Aisling doesn't mind me putting a Spirituality link in here)
Fear: the Basic Evil It has an exercise down at the bottom that talks abot how to write out decisions you have been making based on fear (or worry in your case). I think you might benefit from it. I hope you do at least.
