Going against the grain here. And I don't know why people are being so harsh. You're the bride's mother FGS, not some irrelevant nobody just going to a wedding of a work colleague
@Lilygreen42 YANBU, and I think you have every right to feel upset and low about it. And I am sorry you've had a shit year.
However, there is nothing you can do about it now.
Can you and your DD get your wedding attire back out, and both put it on, and get take a few pics with the camera on the self timer, with a nice backdrop like the dining room/living room curtain?
We did something similar. When our DC were Christened in the 1990s, they scowled all the way through their Christenings - (did the 2 together as close in age,) and they cried too, so the pics taken at the Christening/on the Christening day were not great.
So before we made the Christening album, we took a few more pics at home, (the following week,) of just them, me and them and DH, and then the two of them with their grandparents, all with our 'Christening' outfits on... and got them developed too (pre digital!)
Then we got the two lots together and it made a nice album. The official ones in the Church, and the laid back casual ones at home. The smiley, cute, nice ones outnumbered the scowly ones LOL!
Good luck. As I say, just both put your wedding attire on, and recreate the day for an hour or so and take some pics. All the best
