Umm somebody help! Advice please and possible pep talk!

Someone asked me to "Hang out" and I've been talking to this person for a bit and its like a date situation or something...cause they said we'll go out to eat....and im anxious and also scarred, like in not a super social person and if we go out to eat...im pretty much will be close to silent through the whole thing...what should I do? I've never been on any type of date (Ugggh I feel like one of those anime school girls 😂)
