Nothing. Nothing is going to stop you now your viva is in sight.
You were good when you started your PhD, and have invested work and time into getting better. You’re good enough now.
You started with ideas and questions, and even if you don’t have full answers now, you know more and know enough now for your thesis and the PhD.
You’re reading this post, so whatever happened to you throughout 2020 and up to today – whenever you’re reading this – you endured. You worked around hardship, overcame challenges and more, whether it was fair or not.
You can make it through your viva now too.
You have got this far.
You did this.
