"Come what may" is similar to "whatever happens". In the future, good things or bad things might happen. Annie is saying to have hope that things will be better the next day, whatever "comes" her way. Ex: Come what may, I know I'll always have you to laugh and cry with! Ex: Jen chose to leave him, come what may.. Ex: I will do my best! Come what may.
