Hello friend @agneslaczo I leave this short poem also in Spanish so you can see the rhyme:
LA HORA HA LLEGADO DEBE PARTIR
¡NO TE VALLAS!, EL ALCANZA A DECIR
NO PUEDO QUEDARME, DEBO SUBIR
YA NO SOY DE ESTE MUNDO, NO QUIERO SUFRIR.
YO TE CUIDO, TE QUIERO AQUÍ.
IRE CON MAMÁ, ESTOY MUY FELIZ.

PRONTO LA PUERTA SE IRA A ABRIR
Y JUNTOS, VOLVEREMOS A REIR
PROMETEME QUE CUIDARAS DE TI
AUNQUE YA LO SE, TU PUERTA VA A ABRIR.

THE TIME HAS ARRIVED MUST DEPART
DO NOT FACE IT !, HE REACHES TO SAY
I CAN NOT STAY, I MUST GO UP
I AM NOT OF THIS WORLD, I DO NOT WANT TO SUFFER.
I CARE FOR YOU, I LOVE YOU HERE.
IRE WITH MOM, I'M VERY HAPPY.
SOON THE DOOR WILL OPEN
AND TOGETHER, WE WILL RETURN TO LAUGH
PROMISE ME THAT YOU WILL TAKE CARE OF IT
ALTHOUGH IT IS ALREADY, YOUR DOOR WILL OPEN.
