Child Wanting to Move In With Siblings

[Najja]

I am 15 years old about to turn 16. I have a horrible relationship with my mother. She is an alcoholic and has made me raise her 15 month old son since he was born. We constantly fight she is neglectful ( I have had a really bad knee for about 3 years and she wont make me a doctors appointment) and many other things. I have an older sister who is about to turn 25. She lives on her own in a 2 bedroom apartment with her boyfriend and she hates the way I am treated here and wants to fight for custody of me. Does anyone know how that would work? Please help me...

She may petition court for custody change

The father may seek a change of custody, if he's in the picture somewhere; the sister does not have legal standing to do so.
