Engleză request for "De Balde"

This is the Spanish part. The title can mean "for free" and "in vain". I think the first makes more sense with the lyrics.

I'll confess to you, I'll gift you
All my bad days
I want to know then
What would you think?

The envy kills you
The envy sharpens me
Is it me?
It's pride the one guiding me

Perfect girl
Lost girl
I would like to know, if you would know about it
What would you think?

Always with desire!
Opportune goodbyes
If you would know about it
Would you love me?

Now. I don't know Galician. But it's very close to Spanish, so I translated the best I could the first paragraphs. Take it with a grain of salt.
Hopefully someone fluent in Galician will translate it.

When they put me the habit
If I ever wear it
When they put me inside the box
If I have to

When a funeral song they sing me
If there's something to pay the clergymen for
And when inside the cave
That still Saint Peter takes me

If only at the thought I don't laugh
With a laugh from the devils!
That to bury, they have to bury me
Even if they don’t get money!
