If you look at your viva prep as just so much to do, a great big problem, and if that is weighing heavily on you – know that it doesn’t need to be this way. Big problems are hard to solve. You can make this easier on yourself.
Start small. Make a little plan. Do something. Read a page of your thesis before you worry about how much or how often you need to read the whole thing. Have one conversation with a friend about your work before you create any anxiety about having a mock viva – or responding to questions on the day.
Of course there are lots of things to think about with the viva and viva prep. For some aspects there are no simple solutions about what to do, how much and when. But you don’t have to start with those big things immediately. You can start small. Solve an easier problem.
