Quoting BαƚMαɳ:" You sounds responsible enough. I think it was incredibly irresponsible of you to get pregnant again tho."
From what you have provided here, you seem to be responsible in taking care of school and work. Although myself being a mother of two and going to school full time, volunteering, it's a hard task...I don't see how you can work 60 hours a week, school work, and take care of a child.
I mean, I know here in NC there are laws against teenagers working past certain hours on school nights, but it could be different where you live. So it would be impossible for someone to work that much here and be a full time student in high school.
