How do I cope with being pregnant and alone?

In the beginning I was with my baby's father like in the first month of my pregnancy. Shortly after I found out some foul stuff about him and I just moved away, I went to Mexico and as I was forgetting him, I realized that I was pregnant. I had my mom when I was in mexico, but now that I'm back in the states, she can't come because of her legal status. I have my brother helping me out with both a place to stay and food. Although I'm hopefully going to start working I can't help but notice how empty and alone I feel. I'm 4 month pregnant now and I thank GOD everyday for this blessing. I just need some guidance or advice as how modern day women do it. I want to be able to deal with my loneliness without the help of an ex or some other dude that isn't my baby's dad. I want to make it alone, atleast till I learn to love myself. Can anyone help me. (By no chance do I want anyone to feel sorry for me, just be sympathetic or empathetic please. I know that there are worse problems out there, I just want guidance or help)
