Megacon: To Go Or Not To Go

So my husband recently bought tickets to Megacon, which I've been looking to for a while because confession: I've never actually been to a convention before. Growing up, I simply never had the money or means of transportation to get to any local conventions and before this year, my hubby and I have really only had just enough money to pay the bills. But now I have a chance to go, and not only that but Stan Lee will be there signing autographs. 

Yeah, that's right. Stan FREAKING Lee -- the king of the nerds! Er Marvel nerds, anyway. 

Here's the thing, though. I'm actually thinking about not going.
Why, you ask? 

Well, I'm not gonna lie. A lot of contributes to my social anxiety. I have anxiety attacks that are triggered by every day ordinary interactions and I really don't want to humiliate myself by meeting Stan Lee while I'm crying and hyperventilating. 

Not only that, but a few years ago, I was actually publicly -- well, as public as you can get on the internet -- humiliated by a well known comic book artist on their blog. I'm not gonna say who or what happened because, honestly, I've deleted any screencaps of the convo, and have really just been trying to move on from that situation. The point is, though, that person was one of idols and they were a total, freaking, dick and long story short, they basically shat all over my childhood. 

Who wants to go through that again? 

I mean, I read online that Stan Lee is supposed to be this ridiculously nice guy, but I really don't feel like testing my luck, especially since I know that I will definitely have an anxiety attack as soon as I even get a glimpse of the guy. But at the same time, he and Jack Kirby are responsible for about 95% of my childhood -- the parts that have yet to be destroyed by the interweb, anyway. Every morning and afternoon, my brother and I would be watching some form of Spider-Man or X-Men.
I don't know what to do, guys.
Honestly, I'd probably be happy just staying home reading and working on my writing. But my husband thinks that if I stay home, I'll just be making a huge mistake.
What would you guys do?
