Перевод - Испанский-Французский - lloro por los momentos perdidos y los...

"le fouillis" would rather be relative to a woman's handbag I would say "les erreurs" instead.
I suggest : "je pleure les moments perdus et je regrette profondément les erreurs [passées]

I'm not that sure about the original text though, is it some nostalgic words, about the past, or is it just someone who hates wasting time?

las confusiones = the mess/the troubles/the misunderstandings

The intention is apologizing for the trouble the writer may have caused, I guess.

Oh? So "le désordre que j'ai pu causer" would match the meaning then.

("les ennuis que j'ai pu causer" is not obvious with the few context we have)

I'll edit with that if you don't mind.

Edit : Another edit that would be necessary is "déplore" instead of "pleure", (unless the guy says that with a guitar from the street to the balcony where the addressee would stand )

What about "soucis"?

No, the text says "cry". The guy cries for the lost moments.

Well, sounds strange to me, we should ask Guilon as my Spanish (same as with my German and my Norwegian) uuuh...is not that good!

Good idea!

hello everybody, I wrote the text. "Confusiones" means the misunderstandings, I think but I do not know this word in French. Erreurs can be right if can be used as misunderstandings in communication between people who do not use their mother language.

Thanks for assistance!!

"quiproquo"?

voilà!!

I would translate "las confusiones" by les malentendus.

"Quiproquo" is of course correct but not seen as usually in every day speech.
