This rant is a long one....sorry

Am I justified in being angry with my in-laws or are my crazy infertility emotions getting the best of me?

Yesterday we went to the in-laws for Christmas. Dh's mom is crazy about insisting all of her children are present at some point (at the same time) so everyone can open presents all together.

Anyway, to make a long story short we don't get along with one of Dh's brothers and wife. They're really crappy people. And, they have a baby. Needless to say, I'm having an incredibly difficult time being around babies right now (failed IVF cycle this month, we were told using my eggs will likely not result in pregnancy for us ever).

When we get to the in-laws my MIL tells me that said BIL and SIL will be coming over shortly. I ask her why they were coming back over (they were over there all day). I tell her that we waited until they left to come over (she knows we don't get along with them). Then she says "well, I want MY family to be together on Christmas." I told her that I couldn't be around their baby right now and proceeded to start crying and told them in a sobbing ramble how we just had a failed IVF cycle this month and would likely not be successful in the future with my eggs." MIL just looked at me and said "Oh, we didn't know." Then she says, "well you can leave if you don't feel comfortable being here but I want my family here on Christmas to open gifts all together." As I'm still sobbing I say "DH is my family too."

As I try to pull myself together in the bathroom BIL and SIL show up with their baby. The entire time I'm trying not to cry. Then, my MIL proceeds to sit next to me on the couch and bounce the baby on her lap and talk to her. What the hell?! I don't normally think of her as a malicious person, but seriously? If you're going to do that, could you at least not sit by me?

Then, later on FIL tells us "oh did you hear about your cousin Jill? She had her baby last night...."

Thoughts?
