Mom cancelled my bridal shower without talking to me..help!

Sorry for the long post. This is actually the abridged version. This may also be a rant but I also just don’t know how to move forward and would appreciate advice. Thank you!



My bridal shower was booked in March for July 26th. Given the current circumstances and the fact that it’s a month an half away I wanted to call the restaurant thats hosting the shower to see if they have new policies (headcount, room changes etc.) My mom is paying for my shower and since she put her name down I thought it would be best for her to call the venue (it is her credit card after all you know) I asked her to call just to see what the venue would say so we could plan accordingly like either postponing, cutting the guest list etc. Again, just to see what they would say.
She calls me after speaking with them and says she got a gift certificate for the amount of the deposit and CANCELLED my shower. She did this without speaking to me first and relaying what the woman on the phone said. It turns out the woman offered the gift certificate OR postponing to a future date My mom’s reason is that she doesn’t feel comfortable being in a room with 25 or less people on an outdoor patio for my shower. My mom is also overly paranoid with a lot (not just this) and she will act on a whim instead of logic. But I get it! Things are uncertain now and I don’t want anyone to be uncomfortable especially my mom. I just wish she talked to me first before making any decisions. I had just started calling those I wanted to invite to see if THEY would feel comfortable attending. I got a hold of half of the guests and all but two said they would come. The other two were going to be away.
I told my mom that we may have lost our leverage with the restaurant bc now we don’t have a booked event with them and if they wanted to they could charge us whatever they wanted now to make up for lost business. She says businesses will be desperate for money so we should be in good shape but I told her that’s exactly why they could charge us whatever they wanted to rebook. Or if we went somewhere else they could also overcharge us.
I want to call the restaurant back and see if I could work something out at least having a day booked even if I have to postpone. I’ll put the deposit down myself! I just don’t know what to say to the restaurant and hope I don’t make it worse.
