I really could use some advice ladies.

Alright so be warned this is kind of a long one but I really need some help with a couple decisions here. I'm currently 24 weeks pregnant with my first and my husband is military and stuck in a state across the U.S. from me. We are unable to be together for awhile due to this. So I live with his parents(who I literally didn't know until I moved into there house about a month and a half ago) because my mother just didn't have room for me in her little house and my in laws have an empty mansion. Now to crack it down here, I'm flying out to where my husband is for a couple days for the holidays and I'm planning on bringing back our 11 pound tiny little ShibaInu dog. Now my mother in law is making an absolute huge deal about this because she has an aggressive dog at the house hold that is always gated up in the living room because if he gets out he'll even bite me, stressful right? Well anyways she says if he doesn't do well with my pup being there (and he won't, because he's already freaking out im there) then I need to find a new place to live with my pup. Lol, and I'm starting to get that nesting urge but I feel putting anything up at this point is a waste of time because I'm probably going to have to move and I don't even know where I'd fucking live and like no one is helping me here, do anything. I'm planning my own shower and paying for it all alone and everything, I even had to move all my boxes up 3 flights of stairs alone 5 months pregnant, as they all watched. And I'm sure I'll have to take everything back down stairs alone again at 8 months pregnant because of the whole dog situation. But she has to come back with me, we have no choice but to bring the dog back. And I'm not getting rid of my dog over having to live there with her for such a short deration of time, it's literally only 3 months. And she's making the hugest deal out of it. And I'm also like certain they don't even like me, and I never did anything wrong but I just get that super bad vibe when I'm around them like I can feel it kinda thing? And my mom just got a new house but can't have my pup there and I'm just not sure what to do right now.... like I really need help and someone to talk to and all my friends have been so shitty lately and I'm stressing so bad and I'm just so depressed. I'm also working right now 25 hours a week and trying to schedule baby appointments and shit is so hard cause I work 11:30am-5pm and I'm just really starting to feel like I'm not cut out for this. 😔 I've been in the hospital with problems this pregnancy and I'm always in so much pain I can't even sleep at night, I'm 24 weeks along and already having contractions and I believe it's from stress but every time I talk to my husband about it he just says sorry.... like I work with my father in law and he won't let me take any time off for appointments and if I do he gets so mad at me and guilt trips me. But my husband doesn't want me to quit because money will become tight. Like what the fuck can I even do at this point.
