Baby shower today 😕

I need some encouragement today. I’m supposed to go to my younger brothers and his wife’s baby shower. They weren’t even TTC and she just got pregnant which then rushed the engagement and now their married. Truthfully, she’s awful so rude and disrespectful to my parents. She’s complained the whole time about being pregnant and how if it was a girl she was going to be upset. Ummm you should just be happy you’re pregnant!! Anyways I’m dreading this and might just back out all together because it’s too much. I didn’t even buy a gift because looking at baby stuff was just overwhelming and it hurt. My Husband and I have been trying for two years now and I just finished my third round of clomid so my emotions are all over the place. I’m absolutely dreading the questions, and the “you’re next!” Comments. Help! What do I do?
