Feeling pretty upset

I need to vent. I’m pretty upset and I know hormones aren’t helping. My step mom who is pretty much like my mom is talking about going to Israel with her church. My first reaction was great go have fun until I saw the dates. She’d be gone dec 9th through the 19th and I’m due November 30th. This is my first so he’ll probably be late and even if he’s not what if I need help or what if god forbid something goes wrong or if I need her for some reason and she’s half way across the world. Idk my feeling are just hurt.
