At least she has the support of her friends, and perhaps, somepony more than just a friend to help her.

This story is a sequel to Critical Mass

Two months have passed since Twilight was rescued, and since then, she has been constantly exhausted, worn out, and easily ran down. Her outlook is far from hopeful in her vulnerable state, but Rainbow and the rest of the princesses are there to help her start the long road to recovery. Perhaps the Crystal Faire, the celebration that the Crystal Empire is most known for, a prominent display of joy, love, and hope, will be just what she needs to realize that tomorrow will be better than today. A hope that things will improve, even if it isn't overnight.

This story is completely written, except with the possibility of revisions of the last chapter. Edits of the remaining chapters are still in progress, but a new chapter will be posted every two weeks until completion, barring any unforeseen problems that arise.

Twilight is Rainbow's best friend, and Rainbow is Twilight's best friend. Both of them are struggling with their feelings and what happened, but Rainbow has promised to be there for Twilight, and she will keep her promises, even as the consequences reach a boiling point and threaten their fledgling relationship.
