I Am Struggling To Keep Myself Together

I am a single mom to a three year old boy. Three months pregnant. The father of my child(ren) has been physically abusive. He has lied about other women. Claims he doesn't know why he does it. I live with my mother and her boyfriend. Her boyfriend has molested me multiple times since I was fourteen. I haven't slept in years because I listen for someone trying to open my door. Less than a month ago he was driving me home from work and out of the corner of my eye I saw him touching himself through his shorts. Completely erect. I immediately told my mom and once again she took his side. They claimed he had a rash. She didn't consider my feelings at all. I have to move by July 1st and I have nowhere to go. I have no family. I have no one. I work forty plus hours a week as a server. I've had a horrible fever/cold this past week. I try to stay strong in front of my son because no one should have to see their mom cry. Everything is horrible. I have no one to talk to about this. My life has never been easy. I thought the darkness in my life was over but once again I am facing it. These pregnancy hormones have me feeling horrible about myself and everything else. I can't help but blame myself for everything. If I would have made better choices? I don't know. I just want to sleep until everything is over and makes sense again.
