Bonjour! I'll give it a try
"Si l’on croit les recherches psychanalytiques les plus approfondies, c’est l’émotion qui donne un sens aux évènements de notre vie."
"If we trust the most completed psychoanalytic researches, it's obvious that emotion is the one giving sense to our life's events"
But I'm not entirely satisfied by this
however, I think if you just need to catch the meaning and not write a thesis or poetry over the matter, it may be good
PS and it's either "Traduisons" (let's translate) or "Traduction" (translation)
(for your thread title)
