Help me keep my kids with me

Hello my name is Dailin, I have moved from Miami to Missouri because I had lost a house in a fire in April 20th and we want a fresh start somewhere else. The father of my kids doesn’t want my kids to move and he took me to court to keep the kids with him, the judge has ordered me to take the kids to Miami and I’m dying of desperation here. I can’t live without my kids. The judge give me the “privilege “ to spend the day after Christmas until January 2nd with them so they can come home and expend that special celebration with my and their older brother who don’t see the kids since August. I can’t afford the plane tickets to bring them here and I don’t know how to tell my little girl she can’t be with mommy on this special days, I don’t know what to do, I need Santa read my letter and help me bring my kids together for the holidays. I really appreciate any help lil or big. Thank you very much.
