A while ago I got an invitation to a wedding. A former friend is getting married (I wouldn't say we're still friends since I haven't seen her in years but I guess I can say we're acquaintances or something). Here's the thing, I can't go. To be honest I don't really even want to go and that's because of my anxiety (people I've never met before, noises, loads of external stimuli etc). But yeah, even if I wanted to go I doubt that I would be able to. Mostly because it's in the end of August, which is when I need to be back in town due to the next semester almost starting but also because I'm supposed to meet up with the other students who help out teaching anatomy for some information and some training I guess (ugh, I'm so nervous already). I'm not sure exactly when that is though.

Question: how do I go about RSVP-ing that I can't attend the wedding? Thankfully you can RSVP via email so I don't have to call anyone but still. I don't know how things like this work. Are you supposed to explain why you can't be there? What do people usually say? Mastodon, if you see this, perhaps you could help me out a bit? I mean, you're Swedish too and I perhaps you know how these things work here in Sweden?

I really need to get this over with. I got the invitation quite a long time ago (last day to RSVP is on the 15th of July).

Thanks.
