Stressed out

I don’t know what to do. My mom isn’t feeling good. She’s been sick, throwing up and lying around all day. I’m scared something bad is going to happen to her. I lost my dad in 2020; I don’t want to lose her either. My grandma is trying to make my mom go to the hospital but she doesn’t want to. I’m 6 months pregnant and I have to call out of my job and hope that I don’t get fired so I can watch my little sister. I’m trying my best to stop crying so I don’t stress my unborn out, but I already know what it feels like to lose a parent.
