Monster-in-law 😡💢

I'm about ready to tell me "mother"-in-law if f*ck off! Last year I got married but because her youngest daughter decided to come over to my house drunk (almost driving her car through my garage), assault my husband, my mother and me - also blaming my miscarriage on me - she hasn't really talk to me. So my mother planned my wedding shower, even told my monster-in-law if she wants to help to let her know. She didn't say anything or help. So now that I'm almost 35 weeks pregnant she wants to plan my "baby shower" with her eldest daughter. And won't even include my own mother (this is my moms first grandchild my monster-in-laws second) saying she shouldn't have a say in it because she wasn't included in my bridal shower, she's not my mom! And wasn't even talking to me! Shes driving me INSANE asking me why I don't have this or that on my registry. I answer and asks again and again. She's picking a fight over the fact that I don't have a mattress, crib sheets or blankets on a f*cking registry! Like WTF she's bitching about what colour scheme the nursery is going to be even though my nursery isn't even finished let along I don't even have my crib asembled! I tell her my nursery colours and she's still asking what colours we're doing so she's like "fine I'll just buy pink and purple" I'm having a boy and she knows this. She's pissed my husband and I off so much that I'm about ready to snap at her and tell her to forgot the whole damn thing because I'm not even going to show up! It's ridiculous! I'm trying to be nice because she's my husbands mother, but she's on my last nerve! Not to mention the fact that I'm getting bitched at for not answering her when I'm working! I'm not even sure what to do anymore, I don't the stress of this let alone the fact that I didn't even want to shower to begin with or have a say in it! I don't even know who's invited, I don't know what the cake looks like or the invitations. I know literally nothing about my OWN baby shower!
