It will take far longer than a month or two for a minor to "get on your feet", if by that you mean establish yourself so that you no longer need any assistance. But for what it's worth, in the interim before you are a legal adult and can do such things for yourself, the family that you are living with will need to have legal authority to do such things as enroll you in school or get you medical care. That will most likely require a court order.
It would really be much easier if you waited until you are 18. You can then sign your own contracts and enroll in your own health care and will not need someone else to front you.
