Learn English – Use of “Who am I” and “Who I am?”

differencesmeaning

I am confused between these two: "Who am I" and "Who I am"

I read this phrase: "Do you know who am I?" – The person was threatening someone.

But what is the main difference in using these?
"Do you know who am I?" or "Do you know who I am?"

Please explain in which case we use what?

Sitting at the end of the stairs, sobbing, having lost my love, career and self-respect, I say to myself, "Who AM I? What is the purpose of my life?" See, here it is a question. That's why the helping verb (am) is coming before the subject (I).

I ask myself who I am. Here, it is not a question, a mere narration of what I ask myself. So, it is not ending in question mark, plus, helping verb is after the subject.
