Try to find little compassion? It isn't like a WAS wants things to disappear because they don't feel bad and don't want to help the LBS.
Rather, the WAS feels horrible, so horrible they don't even KNOW how bad they feel. Wanting the whole thing to go away is a symptom of their inability to confront themselves, to really be honest with themselves. For them to really see themselves fully is an incredibly painful process. So, they try to avoid that pain. Thus, wanting things to go away is a defense mechanism.
If they felt just fine about what they did, they would have no problem being honest about it and supportive toward the LBS.
In any case, viewing a WAS with compassion does NOT mean that an LBS should not express her feelings, set boundaries, and ask for what she needs.
