Will the judge take my choice of living with my mother into consideration if i have an reasonable explaination?

I am a 14 year old female, whos been living with my grandparents for about 10-12 years. I feel i have been neglected, and outcasted for about 5 years. I have tried to tell my grandparents how i was feeling, but they always find a way to turn things around and make it seem like i am doing something wrong. Recently, they have filled out paperwork requiring adoption. I honestly do not want to live here anymore. I am terrified to tell them that i would like to live with my mother and brother. I have informed my mother about my decision and shes agreed to do anything she can to help me live with her. If i were to tell the judge, that i would like to live with my mother, and had an reasonable explaination, would he/she take my choice into consideration?
