טקסט מקורי - צרפתית - Je suis comme je suis et je sais ce ...

Hi, gamine!
Can you please help me here? I'm in doubt with the second part of the sentence.
Is it: "and I know this (thing) because I am an adult"? Or "fait" is a past participle and here we have a passive form of "faire"?
Thank you so much. I'll give you half the points of the translation, ok?

"... and I know what I'm done for."

I am what I am, and I know what I'm done for (or rather "what I'm made for"

Depends on the context, if it's about a work, a task, or one's fate
