Going to my husband's work event next month and stressed out

So, to give the context, I (25F) will be attending my husband's (30M) work event party thing next month. I am dreading going because it's a formal event and he works at a very big company as an engineer.

He is everything that I am not: smart, talented, funny, very outgoing and extroverted.

I am extremely shy, awkward and have no education. (Drop out lol). We don't have kids yet so I can't talk about that and I quit my job last year so I have no idea how I'm going to interact with these wives of all of these professional people when I have nothing to relate with.

I am young and inexperienced and currently a sahm wife with two cats. I love gaming lol, but I doubt anyone else does. I really struggle to keep a conversation going, I just hate talking unless it's something I really enjoy or I'm drunk.
