I'm going to an actor/filmmaker pop up event but I'm stressin' about it

I have a post on here that relates to this for reference entitled "Frustrated actor"

So this Wednesday I'm going to a network event for actors/filmmakers etc. I would be excited for it because this could be exactly what I need to revitalize my acting pursuits since I haven't gotten a single audition. The only thing is every time I've been to these type of events, they'd be all nice and act like they wanna network in my face, then after you exchange contact info, it's like you're dead in the water. So I have that kinda stuck in my head, almost knowing any "connection" I make there is just for the moment. Most people are such flakes today that whatever in person interaction you have with a new person, you sort have to take it with a grain of salt these days. At least that's how I'm looking at it because from experience that's just how it's went for me. Plus I feel a bit played already because I was invited to this event thru a casting site called backstage, from this guy who runs a film production company. At first he said that I'd be on the invite list for a free pop up shoot, to get professional footage for a demo reel. I was told to register when he first contacted me, which I did. Little did I know a week later, it never went thru or so he said.

So I had to do it again but by then so many other people had signed up. I can still go to the event but now he's telling me how random people who registered will be "randomly" picked (top 5) to try it out for free. He told me a week ago he could bump me up to the official invite list, when I asked about it again yesterday...no answer. I'm still gonna go to the event because I'd be stupid not to go, because it's not like anything has been happening for my acting career..it's just all of this is leaving a lil bit of a sour taste in my mouth and it hasn't even started yet. I swear before the event I'm gonna pop a few ativans, so I can be relaxed in there and I don't make a fool out of myself. Oh and I'm worried and stressing because there's a chance this one actress that I regrettably worked with is gonna show up as well. The reason that would be bad is because we do not like each other for reasons I won't get into. She books all the time so she is busy a lot anyways. So I'm hoping she isn't there but then again if I got the message/invite to go, I'm sure she did as well because acting in my area is a small market/community as it is and she's been booking like crazy (pretty privilege is real) I may trigger some folks by saying that but it's the sobering truth
