I hope her Universiade experience will be useful to her: an international medal and two fairly steady skates. A good thing to remember to make yourself believe you can do it.
I think Stasya is learning to work around her nerves: compare this year to last year's worlds. Even when she bombed the opening combo, she tried to work around that and save what she could.
What she needs now, imho, is to believe in herself. In her ability to win and to do great.
(I think she knows that, too. Her personal Instagram handle seems to be 'urdoingamazingstasya', a kind of a personal affirmation)
