Are there any other mommys to be without parental support?

I'm 18, and i'm 6 weeks pregnant. I moved out of my moms house last March and my father hasn't been a part of my life in 14 years. I currently life with my boyfriend of (officially) 8 months, and his family. His brother already went through a teen pregnancy less than 2 years ago and my cousin who i'm really close to, more like a sister, had her first baby at 18 so my family went through it as well. I just feel like a disappointment but I don't know how we're going to support a family without the help of a 3rd party when we need to work or go to school. Suggestions? Anyone else in a similar situation?
