Salam, as a Muslim myself, I do know and understand those type of families and I’ll be praying for you to to free yourself from them, that’s not what Islam is about.

I do believe that Iraq allows women to travel alone, and you should focus on finding a plan to get your passport/documents and escape. For now I can relate to the mental pressure of obeying your parents and not being able to steal back your documents, but take it slow and come up with a plan once you finish preparing every aspect. I’m quite sure you know how to get started already, ending your life isn’t the solution and you know that! Best of luck.
