Welcome Kathleen, thank you for signing in and sharing with us.
Busy is another form of workaholism. If I am not mistaken, there are several post on this topic in Other Addictions.
Just another tool/substance we can use to escape our reality and not look at ourselves. If I look at you, I don't have to look at me. If I am busy doing, I can detach from my own stuff and get into self-justification, after all I can say, "You are much sicker than I am."
There is a meditation book that helped me, "Meditations for Women Who Do Too Much" by Anne Schaef.
