IELTS Exam Fear

IELTS Exam Fear Hello Guys, I'm planning for my postgraduate studies abroad. To do that, I have to clear IELTS. For the past 1 week, I'm unable to sleep or take a pleasant nap in fear that I will stutter super bad while my speaking session. I've fluent speaking and cohesiveness with lexical reasoning while talking to my close ones. But with unknowns I stutter bad, it makes me uncomfortable to breathe and think. Thinking about the speaking session, I'm in a subtle fear of even booking my IELTS Test Dates. How shall I overcome my anxiety? Please share your experiences. Thank You!
