So over the competition

I seriously am so fed up with my mom's side of family. My cousins daughter so my 2nd cousin? Is pregnant and due a couple days after me and ever since it's been out they have done nothing but made it seem like a competition. I mean from the start I told the family in person before posting anything about it on social media and she right away does it on facebook. So when I went and posted my announcement she had to post a stupid status in regards to it. How everyone is pregnant all because she said she was. Then at my grandma's birthday when my aunt and uncle were talking to my husband and I about the pregnancy and how it happened and such her mom and her came and butt in making it all about her. Oh then my husband and I paid for a early gender scan because we wanted to tell our parents at Christmas what it was. Her mom right away didn't say congrats or anything positive about it. All she said was "oh are you going off the heart beat?" And once I told her no we have a picture of the penis she was like "Oh Sierra is having a boy and that's going off heart beat". Like ok cool. You can't go off heart beat but hey atleast they got lucky and it is a boy I guess. At my baby shower my cousin showed up, her daughter didn't (the one actually pregnant) and couldn't stop talking about her daughter. And she kept saying things like"this is your day I don't want to make it about sierra" ...except she did. And she even stole everything from my shower for her daughter's shower. Except the theme will be different. And now she's bragging about how she's dilated 3cm already.

Ugh. I am trying to be so humble and just ignore all of it and let it be but I've seriously had enough. I mean my sister's and I went in on a really nice crib for her and she didn't even tell us thank you or anything. And it's just so rude. And for her and her mom to make it seem like this is a competition just grinds my gears because it's not. I'm sorry I'm actually trying to enjoy my pregnancy and cherish all these moments with my husband. It just hurts and honestly puts me down so much. I just don't get it. I don't know if she's jealous because I'm more so in a better situation than her or what but it's just so damn stupid.
