J' essaie : tu me diras si ça va:
I was schoked, my eyes wide open. I didn't want to be in that place. The police took the baby and threw him down on the floor(as a commodity, c'est un peu fort). I was very (so) scared. The baby went on crying louder and louder. The officer was remaining indifferent and continued to abuse the woman (and her child? abuse = souvent violer, si c'est maltraiter alors) continued to mistreat the woman and her child. I would have love to help but I was terrified by this scene. I said to my mother "Save this woman and her son". I asked questions -tu poses des questions ou tu TE poses des questions, si c'est la 2 c'est I was wondering, my mum was breathless (à la place de focus by this scene, pour éviter de répéter trop 'scene'), she was watching saying nothing, still , (=immobile) maybe even more shocked than I was. The police left with the woman, abandoning the baby on the floor.A lady came and took the baby away. (sum = somme ) After that, (When it was finished ou over) we came back home speechless, upset by what we had seen. Those images are staying in my mind, I'm asking me a lot of questions; I'm not able to eat nor drink.Every night I have mightmares, I have to sleep in my mother' arms.
J' ai fait de mon mieux en espérant que c'est bien ce que tu voulais dire.
