I'm not sure if you'll see this but here it is.

I moved out from an abusive home when I was 17. I had graduated high school, worked full time, and had my own place. I was not getting any financial help from anyone. One day I was hurt on the job. It was not a big deal - I broke my toes, but I was a waitress and in order to not lose my job they sent me for x-rays. The hospital refused to do anything for me because I was a minor. They told me I had to have an adult sign for me. I told them I lived on my own, etc etc, and they told me they still couldn't do it unless I was declared an emancipated minor.

They flat out refused to do anything, even something as minor as an x-ray and I certainly wasn't calling my father. I finally had to call my grandmother, and they let her sign for me. The point is, if you want to stay independent, and if you are working, you should try to get yourself declared an emancipated minor. I had another 8 months or so until I turned 18. I asked my stepmother about it and she refused to declare me emancipated, so I just had to deal with it until I turned 18. However, since your mom bailed, I would think that you should be able to go to court yourself and get declared.
