Ry, it's clear to me that anya is stubborn yet intelligent. While she recognizes that the advice she has received here makes sense and resonates within her, she is determined to sweat this out to the bitter end on the marginal chance that it will do a 180 degree turn around and yield dividends down the road. After all, miracles do happen, right? That's what people who are diagnosed with stage 4 colon cancer tell themselves, too.
tl;dr Sometimes people have to learn the hard things the hard way.
