Retrieving an email sent by mistake on Laposte.net

Hello, like all the desperate people who post this kind of topic, I accidentally sent an email to the future woman of my life... Of course, without going into detail, this email is likely to change my destiny. So, I would like to know how to cancel an email that has already been sent and not read. It was sent via Laposte.net to a Hotmail.fr address.

If someone can "save" my life... I thank you very much.
