Bridesmaid fall out

2 weeks to go before wedding and I am due for next hen this weekend.

It's restaurant and cocktail. Due to covid it got cancelled, 3 bridesmaids all sorting it, one went to hospital so another sorted it and said it was too stressful getting deposits back so then I said I would do it. Couldn't get the deposits so paid £150 out of own pocket. Since then I've been contacted loads. All I wanted was for them to sort and one less thing from me.
The restaurant called again and I got angry in our chat saying I felt let down and that it was a simple task.They've come back saying I'm ungrateful etc. I've apologised but not sure what to do. So upset.
