What should I expect for our photo shoot? I suffer from anxiety...will they direct us?

My fiancé and I have a photo shoot in two days. It’s our first one as a couple/ I’m so nervous and anxious. I suffer from social anxiety.

What can I expect? Will it be awkward? I get really weird around people...I don’t like showing PDA in front of others.

I really really want beautiful photos to capture our love for one another, but I’m so anxious that I’m thinking of backing out 😭
