Friend invited me to hang out with a group tomorrow...

So my best friend - Sara, another close friend - Stephanie, and a girl I like, who fancies me back - Julia , is going to be there. But it's going to be a group of like 8+ people...
As if casual social events arent bad enough, I'm even worse in groups. Yeah, it's possible - who knew?
And Julia was quite shy and nervous last time I was around, so it was kind of awkward every time we (or I...) would try to make conversation.

You have no idea how badly I just want to whip up some random excuse and say I can't go. But it would just feel too rude since I've already done that multiple times. And the fact that Julia's coming would make me feel like a complete *******... You know, seeing how it's Valentines day.

So I don't know, guys. Just venting. But opinions and advice would be nice.

I'd say go. Push yourself out of that "comfort zone". You have no idea how many times I've also declined to go out with some friends just because of my stupid phobia. So, just go for it. You'll probably have tons of fun

I'd say go as well. More often than not (at least for me) what happens is you scare yourself into not going and then really regret it later, and feel like you could've gone :/ Even if it turns out to be a disaster (which it most likely won't) at least it's an experience, and possibly something to learn from.
