*hugs* I can empathize and that was just from TTC. I am so thankful at I have never had to also deal with the pain of a miscarriage. I have a friend who is now 3 days overdue and all through the pregnancy all I heard was complaints about how fat she was getting and how uncomfortable it was and how annoying it was when the baby kicked etc. Took all my energy not to scream at her to just be thankful because I would have given anything to be 'fat and uncomfortable'.

I would suggest giving yourself a little distance or even straight out saying (providing she's not the kind of person that is easily offended) that it's too hard for you to hear the complaints right now.
