DD2 get married next year. she does not want DD1 as a bridesmaid. Not to drip feed but DD1 has mental health problems and DD2 is worried that being in a crowd and in the spotlight, having to make small talk etc which are all things that DD1 hates, will be too much.
DD1, i suspect doesn't actually want to be a bridesmaid for all of the reasons above, but is giving the impression that she has been overlooked in favour of DD2's friends. she has been asked to do a reading instead - shorter time in the public eye - and agreed, but there is friction and comment from the wider family. Personally, I genuinely don't care if DD1 even attends the wedding. if it's too stressful I'd rather she wasn't there, but this seems to be an unacceptable train of thought.
