bonjour je doit faire un poème en anglais de 3 couplet avec la forme used to si quelqu'un m aide se serait super simpas

first of all t'm not poet but i can halp you

my smile was shining
when i used to play with toy
when i was yong
fool things i used to do
and may be gloomy
when i have to do like everybody
when i was yong   fool things i used to do
 but not now unfortunately
i used to play by long
Actually my world innocent has gone
and its  recall stay  living in my heart
