And I will try to fix you (E eu vou tentar te "consertar").

Não achei as traduções muito convincentes...

"Fix" não poderia ser algo como "dar suporte/apoio"?

"To fix you" could have many meanings.  There is no way I know of to get into the composer's brain and see what he was trying to say.  Let's look at some possibilities:

And I will try to fix you = And I will try to catch/protect you (used in weight lifting, gymnastics)

And I will try to fix you = And I will try to give you an injection of illegal drugs

And I will try to fix you = And I will try to repair/correct you

And I will try to fix you = And I will try to neuter/castrate you (used by veternarians)

Believe me, "to fix" has many meanings.
