ADOS2 assessment next week, extremely anxious

Hi, I finally have my face to face assessment next week after two and a half years. I’m so anxious I can barely function. I’ve been told it will be ADOS2 that will be used. I’m really worried that it won’t be suitable for me because I was a nursery & infant teacher and can therefore role play and improvise (in front of young children anyway). I spent a long time learning how to do this because I desperately wanted to be a teacher. 
Can anyone give me reassurance about the ADOS2? I’ve only read negative things about it. Thank you
