I feel like it's just now sinking in!!!!!😩😩

Ill be 34 weeks on Thursday. I had dreams ALL night about SIDS, giving my baby CPR, and my baby not calling me mommy :( because I'm 19 and live with my mom. Which really shouldn't matter but my mom is very offended that I want to move out, buy all of the baby things myself (along with my SO), and just be independent about this pregnancy in any way I can. She discourages me from taking strides to help move out and become independent, other than going to college which I am going to do in January. It's so frustrating. She has said to me "you know you're gonna have to set boundaries bc we are gonna wanna hold that baby all the time"... ok? And upstairs I have like a studio apartment almost. It has a bathroom, couch, bed, everything besides a kitchen but I have a mini fridge and a bottle warner... my mom has 4 dogs and 5 cats downstairs which are all clean and friendly but her little dogs have made the carpet smell terrible. Upstairs the carpet is clean so I turned it from a very large bedroom to this studio. My mom discouraged me from buying an 1800 dollar couch for 500 from someone I knew, (I did it anyway) because I didn't feel safe having to go up and down the stairs to get to the nursery if I needed certain things and I didn't want to be carrying the baby up and down stairs in the middle of the night. She told me "hopefully you don't keep that baby cooped up upstairs. She'll be antisocial." Like what? We aren't hiding upstairs, it would just be like a small home? Idk. But it's causing me to have like 3 nightmares in one night. Could just be that reality is finally sinking in, lol. Any tips?
