Princess of Friendship in fanfics.

Time after time I see fics that revolve around one simple idea - Twilight only can be friends with Pinkie, Rarity, Dash, Fluttershy, and Applejack. They all have one common scenario - that after hundreds, or even thousands of years after their death Twilight still unable to go over their demise. And obviously unable to make any new friends. She still mourning, she tries to find a way to bring them back or try some way to commit suicide to reunite with them. People do understand that they pretty much write her as a failure as Princess of Friendship? That even after hundred or thousands of years she unable to make even a single meaningful connection? Yeah, Princess of Friendship right here.
