Hi Jaceycat,
I'm also on step 4. It is hard, but cleansing. I am anxious to finish.
I bought a Step Four Inventory guide at my meeting which has been great to help you through the inventory. If there's not one available at your meeting, you can order from the website
www.oa.org
You can also find 4th Step guidance on:
*Pages 34-43 in the Twelve Steps and Twelve Traditions of Overeaters Anonymous book and
*References pages 64-65 in the Big Book
Hope that helps.
Charlene
