How to handle meeting my fiancé dad

My fiancés dad is coming into town tomorrow and staying for a week. We’ve been together for three years and due to the pandemic and health issues I’ve never been able to travel to his home state and meet his parents/ family. We’ll now he’s finally coming, I’m 39 weeks pregnant and being induce on Dec 1st. We’ve talked maybe a hand full of a time over FaceTime but I have severe social anxiety. Like full blown hyperventilating unbearably lightheaded anytime I’m around more then a couple people I don’t know anxiety. And the pandemic had probably made it worse. We have a couple things planned to do our while he’s here but after the baby I’ll be home the remaining is the time he’s here. He’s a very kindhearted person and seems genuinely caring (both my parents are abusing narcissistic assholes) I just want to be as social and welcoming as possible while also not stressing myself out. Any advice is welcomed
