Gosh, I hate to admit this....but...
it took me 7 MONTHS to complete this step! (I think I dawdled...LOL)
IMO, you have to remember this step is not about beating yourself up.
And let me tell you, I think it's a cleansing of the mind and spirit to do this step.
If you need help doing this step, there is a booklet you can order from Alanon called "Blueprint For Progress"
