Bonjour les amis je besoin de l´aide pour cette exercice SVP

J'aimerais que vous m'aidiez à vérifier la grammaire de ce texte en anglais et que vous puissiez le corriger s'il est erroné.

Ladies and gentlemen, I thank you for your presence at this magnificent event, first of all I thank all my fans, family and friends for all the support they gave me throughout this season and to show me their loyalty to me. But I must confess a news which is not pleasant for me and will leave you shocked, unfortunately I want to express that I cheat to obtain this important trophy. For me to give this news is very humiliating since I did not get this trophy so crucial to my career as an athlete in a clean way. I want to apologize to my fans, family and friends for having committed this totally immoral action which makes me disappointed.
