Anyone a single parent living alone with their new born ?

I am not a single mom but I do have a boyfriend that isn't the child's father( as he walked out as soon as I told him I was pregnant). I have all the support from my new boyfriend but he's new to all of this and he has his own home with his roommates and I will be getting an apartment by myself. I am so scared that I will be so overwhelmed when the baby is here and being alone. I need advice . Expectations/ advice please. I want the best for my baby.
