Vendors Ghosting?

I’m curious to see if anyone else has had this issue..
Last week we came to the decision to postpone our wedding that was supposed to be on August 2nd.
I was surprised by how quickly dates were being booked at our venue for next year, so I’ve been communicating with all our vendors (since we have everyone booked already) to try and find a date that works for everyone. We hired a day of coordinator pretty early on and throughout the planning process she’s been super helpful and good at responding back to emails in a timely fashion. However, I emailed her right after we decided to postpone with a list of dates next year to see if she was available. I’ve heard nothing in response. I know this is a crazy time for a lot of people, so in that regard I can understand, but on the other hand I see her posting on Instagram every day, and at this point I’ve had to make a decision on a date without knowing if she’s available or not. Any advice? Am I just overthinking this whole situation?
