What I have read over the years here is this. It is only a matter of time before you will be dressing again! My experience of purging and then starting again showed me that I was not alone.

Try just underdressing, she will not see anything, yet you will enjoy the wearing certain articles of clothing. The underdressing might provide that outlet which you seem to still need, or want.

The embarrassment, and guilt are both so typical, yet I doubt they are enough to keep you from not dressing again. Why, because you are already looking for an outlet!
