Being a bridesmaid when on spectrum for friend wedding

Hi everyone 

I have been asked by a friend to be a bridesmaid for her wedding and I am really nervous about the whole thing.  I am not keen on noisy environments and looking to get loop earplugs so I can still speak to people.  My family will be there but I still find awkward around strangers and I always mask to fit in.  I am just nervous about whole thing and I have only just recovering from Christmas its just all so overwhelming and yet I want to enjoy it. 

I was wondering if anyone had any advice?
