moodylupin probably has it right. But allow me another interpretation:
In AOB's meteoric rise, Jenny lost her foundation in God. She became so swept up ("I let the trees grow wild around me") that she lost sight of God ("Grew so high hid the sky - Shaded everything I needed to see "). However, she's settling down after this chaos and finding God again.
