I don’t know what to do anymore

I’m currently 28w pregnant with my first child, I’m no longer with the dad after so much stuff I finally walked away. Since I was living with him I had no choice but move back in with my mom, I have 2 brothers and they bring my depression on they have mean things to say about me and my unborn baby. Always joking about punching me in the belly one even fake acted like he was gonna punch me in the belly, they knock on my door when I’m sleeping and always talking about me. I’m beyond depressed and trying to hold on for my kid. I don’t know what to do anymore how do I go about getting help to get out of here? To somewhere safer for me and my unborn baby?
