should I stay in school or drop out and get my GED

So before I got pregnant I was a dropout. I ended up being court ordered to go back school (long story) and I ended up finding out I was 7 weeks pregnant at the clinic at school. I started going to an alternative high school which I attend still but I was in an abusive relationship with my child's biological father and I didn't go to school so I barely earned any credits last year. I'm supposed to be a senior but I'm still a freshman at 17 years old (embarrassing I know). The perks of my high school is that it is specifically for teen moms and they have a day care center on site. But my dilemma is that my family is struggling and I would need to take the bus every morning (actually 2 buses and a train ride) with my newborn just to get to school. It's my only option. Should I just drop out and eventually get my GED and just start working instead? My mom is really struggling and I want to help out. I'm not sure though because then I'll need to find daycare. I'm really worried. What should I do? I regret not going to school before I got pregnant. My life would be so much less stressful.
