Feeling depressed ? Help?!

I am 20 yrs old and pregnant with my first im currently 15w&5days. My babies father died right before I found out I was pregnant. So I rent out a room with one of his family members through marriage but when I'm not working I'm in this room all day. I have no car and the friends that I do have which isn't many either are busy or have better things to do than hang with a pregnant girl. I don't go anywhere. Luckily my mom stays 10 mins away and she's gonna help me get my own apartment this month :). But i just feel so lonely like I have no one to talk to or hang out with. I miss my boyfriend :(, I never felt this way when he was around. I just sit at home , browse the Internet and cry lol. Ugh :(.
