I need help getting my daughter back

Hi my name Is Mitch and my daughters name is Aubriana. She is 10 years old. I lost guardianship to the grandmother about 8 years ago do to drug use. Since then, I've changed my life around. I'm in recovery and I've been clean from all mind-altering substances for over 4 years now. I built a wonderful relationship with my daughter these last couple years. However, her grandmother is fighting me and doesn't want to give her back to me. Unfortunately, my daughter's mother is no longer in the picture and I believe the best place for her is here with me, my fiance, and her baby brother. I have court again November 9th and I am in need of a family law lawyer. It's time to set my pride aside and ask for help. So please help me! I will be truly grateful for any kind of Assistance or help. Thank you for taking the time to read my story. God bless!
