So nervous for our couple shoot I want to cancel... what to expect?

I suffer from MAJOR social anxiety and I have a photoshoot coming up next week with my boyfriend. It’s just a cute couple shoot, but I’m so so nervous. I’m getting anxiety over it and almost want to cancel 😭

We don’t have any photos of us kissing and I don’t even kiss him in front of anyone...I blush too much.

Any tips on how I can get through this? What should I expect? I think that’s what’s really getting to me...the unknown.
