Anxiety with BF family

I’ve been with my boyfriend for 5 months. Everything is great with him! He’s very family oriented and loves spending time with them. But I feel like there’s a big cultural divide between us. He’s Guatemalan and I’m white. When we go to big family events there’s at least 30 people there. I have pretty bad anxiety and there’s times at the party where everyone is dancing and I get pulled into it. Last time it happened I couldn’t stop shaking from my nerves. His parents are very in your face. If I’m not talking enough or verbally showing I’m having a good time they’re also questioning me. Idk what to do I can’t help my anxiety
