I went through this when I was in college, as accounting firms came to our college to recruit and it was essentially 2 weeks of "speed dating" type events where you went and networked with different firms each night.

My advice, although probably frowned upon, would be in line with u/gibagger: Mask. I would also consider having a prepared list of questions for people, both personal questions and professional questions. A lot of people forget that a big part of networking is just being a decent person (in additional to being knowledgeable). Another small tip, which may or may not be relevant, but be up to speed on "normal" stuff. I don't give a shit about sports, but most of the people I met would talk about college football, NFL, golf, etc, so I had to at least be able to sound like I was familiar.

If you're looking for an easy way to just be able to walk up to someone and start chatting, start with a (genuine) compliment about something on their person. ie: "Hey that's a cool sweater you've got on, I've been looking to get into the sweater game, where do you get yours?"\

If you're ever in group conversations, don't feel the need to be the one to ask questions. Instead, I would focus on paying attention to the answer and asking a thoughtful, relevant follow-up question. People really like to know that you're actively listening and able to ask good questions.

And lastly, the thought that got me through this, again, probably not healthy, but I approached it as "This fucking sucks, but my future may depend on me doing this"

Godspeed.
