Help me here please... I dont remember this movies title

I saw this movies about 6 years ago, its about a 6 or 7 year old white girl, she was at the school all the time with an arm cast on his left or right arm, her mom died and she got extremely sad she couldnt believe it, crying all the time, then she was so sad she went to her moms grave at the cemetery and stared to cry over the grave and trying to dig her mom up, then her mom appeared and hug her, then the mom said to her that she will not be with her no more. THE END.

I dont remember if it was a french movie.

I really want the name of this movie so i can watch it again, so please if someone here knows about it, please tell me. Thanks. my email is
