Well, typing so fast to tell someone off is knee-jerky.
Educationally, you have a way to go, by the sounds of it. A 3.1 won't cut it, and the major science courses are tough, so you have quite the uphill battle. Do you have time for extra-curriculars to buff your C.V.? How far away are you from taking the MCAT?
Financially, how much debt do you think the average student has? Is your job one where you can make enough money while going full-time to support a daughter? It's good that you don't have bad credit, and that you are able to pay the bills.
Family-wise: If you're doing medical school, you WILL need them to help with your daughter. This really isn't optional. That's not a sign of weakness, it's just a sign of sound family dynamics.
No Pun Intended? I didn't get that. Anyway, you have a long way to go, educationally, and you need to weigh the benefits of the career vs the risks undertaking this venture will have on your daughter. Make a list of why you want to be a doctor; Is it purely a thing of working in the healthcare field? If so, there are other options which are far easier to obtain. Next, make a list of the negative impact it will have on your daughter: Time away from her only parent, raised by others, stress on you = stress on her, financial considerations, etc. Make no mistake about it, choices have consequences, and they are both positive and negative, so be honest with yourself. Place these lists side by side. Make your choice.
Good luck.
