Getting ready for my first conversation with a native speaker

I've been self-studying for months using just books and flashcards, but I’m terrified to speak. I’ve started using Chickytutor.com to simulate a real conversation, and it’s been incredibly helpful for catching my errors, but I’m still nervous about the 'human' element. What are some essential, low-stakes phrases in Afrikaans I can use if I get completely lost or forget a word that will keep the conversation going naturally?
