Equestria, a land of peace and harmony ruled by the ministrations of two immortal demi-gods.
Everyone living within miles of Equestria know of the Princesses Celestia and Luna, who great wisdom and diligence have served their country for millennia.

Twilight Sparkle, a newer addition to the rapidly inflating cast of goddesses, has since ascending experienced difficulty coping with the attention, popularity and responsibility thrust upon her.
This often causes her to doubt her ability as a princess, and having had a relationship with Celestia has taught Twilight that, unlike her mentor, she just isn't cut out for the limelight.

It's something she is simply going to have to get used too over time.
Besides, if Twilight doesn't adapt eventually then what would she do?
It's not like godhood is something you can just resign from.

She probably would have heard about that if it was possible.

Probably.
