First assesment

It's my first assesment for Autism tomorrow (I'm 25) and for some reason I'm terrified and can't sleep , any advice would be greatly appreciated.  Thank you

    • Thank you everyone for your advice, first assessment went well. Started anxious and got slowly comfortable. Second (and possibly final) assesment today (yes I'm up at 2am again) closer to answers
