Here is a link to a wonderful story about Thanksgiving. Perhaps you can print it out and re-read it each year before this feast. http://www.catholic.org/national/national_story.php?id=34920
May the Lord continue to bless you with all good things. If for some reason life doesn't seem too good for you right now, take a pencil and paper and list all the things you are grateful for - for the gift of life, for the gift of family, and for the gift of God among us and in us through His Eucharistic Presence. You must have lots more "gifts" that you can add to your list!
