I'm so mad!!! Step sister rant!!

Ok so technically she isn't my sister anymore since my dad divorced her mother 5 years ago and I'm fixing to unfriend her on Facebook LOL!! Ok so I just found out she is pregnant too and she is due in December, I'm due next week!!! And all I did was make a comment on Facebook about my due date coming up and how I hope my baby is here before then since last week I was dilated to 2cm.. And then SHE POST that she just got checked today and how she is almost 5cm!!!! I don't know if she was joking or just pissing me off!!! 😭😭😭 I'm literally crying!!! Why I don't know, guess I just feel like my baby will never come.. She just likes it in my belly..
