I don't like ED. Mainly for no other reason than I find her trite and irritating. However, I do think that sometimes peoples' dislike of her on this forum mean that they, unintentionally, come across as a little cold about people dealing with infertility.
Although I find what she writes annoying (as someone who is also dealing with infertility), I don't think saying that you find Mother's Day hard is making it all about you. We wouldn't say that about someone who says they find the day hard because they've lost their mum. There is not a finite amount of celebration available on Mother's Day - one person saying they find the day hard does not remove someone else's ability to enjoy it.
