Oversættelse - Portugisisk-Latin - As saudades não nos matam, apenas nos tornam mais...

As everything you write in Latin, your sentence is of a fine and exquisite latinity; however I'm afraid you haven't exactly grasp the meaning of the source (which certainly is, as it is expressed, somewhat obscure) :

"As saudades não *nos* matam, apenas *nos* tornam mais fortes."

literally : "Nostalgia does not kill us, it just makes us stronger."

It's a little bit nonsensical, in its sham-nietzschean style, but that is it...

Thanks for your remarks. I've already changed it. Is it correct now?

Yes indeed.
