38 weeks and overwhelmed with kids, drunk husband, mother issues and staying in a hotel away from my friends. Am I being too negative or is it really bad?

I don't know what to do, I'm 38 weeks and I am feeling so overwhelmed and I feel like I want to tap out of my life by leaving my husband. Am I being irrational because I'm pregnant? Does anyone else feel like this? 
I have 2 boys aged 4 and 6 and the 6 year old is particularly difficult, has all kind of behavior issues. My husband helps a little but every now and then he gets drunk and gets the kids really hyper, then I have to pick up the mess and deal with him being extremely annoying. 
He dragged us to a new town away from all my friends because he likes it better here (nothing to do with work) but I don't like and i really did not want to go and deal with a major move during my pregnancy. I cried so much for months because i didn't want to leave. I spent my whole pregnancy crying about it. 
We have to rent our new house out all the time to afford to keep it so we're in and out of hotels. It's really hard, I spend my time packing suitcases for everyone, unpacking, dealing with logistics, school, lunch boxes, I have no time for myself. I don't even have time to sleep. 
And I have a very bad and demanding relationship with my mom.... at least she lives far away but it's still stressful. 
Before you ask, I do talk to a professional psychologist once a week but that's not helping at all because I feel like I need to solve my problems as opposed to just talk about them. 
I miss being settled. I am feeling so overwhelmed, my husband is not treating me like I'm almost 9 months pregnant, he didn't really want a third in the first place, and he wants me to work as much as I can all day so we can live the life he wants to live in this new town. I feel like he wants to punish me for having a third child. 
I'm depressed and I can't tell if I'm being irrational because of my hormones or if my situation really is bad and I should leave. 
It's not like I'm being beat up, but I'm definitely not being treated kindly either. He just puts his own needs and wants ahead of the family's. Would I be better off or worst off if I leave? 
We have been together for 15 years.... usually we can work things out, but this time I am too angry that he has dragged us all over the place for his own pleasure and is making me work so hard all day to live the life he wants to live. It's also the 7th time that he makes us move and I am really so tired of it. 
I miss my job and it's impossible to keep a job when following someone else all over the place. 
I haven't had a second to stop and think about the baby in my belly, love her and cherish her because I am too overwhelmed with everything else. 
What should I do? Should I even do something or just wait it out?
