Stressing about housing

So me and my SO (the daddy) live with his mom and it has never been good she used to always threaten to kick me out (even after a really bad car accident when I was struggling to get a job) and even now. She got mad that we didnt ask all of her questions at my first appt. But we had other things on our mind, mind you it's our first baby. I dont know what to do as she got butt hurt over that yesterday and is now saying we need to be out in December (baby wont even be a month old) I dont even want her involved in the pregnancy anymore as I have really high blood pressure and its stressing me out to even be in the home. But we really dont have anywhere to go....my family is in Colorado and already have a full house. Km just so stressed and I cant afford to be stressed for the sake of my baby. I just dont know what to do anymore
