Hello again!

"Ben olmasam da kılına zarar gelmez. Bir dediğin iki edilmez."

Even if I am not with you, you will not be hurt. Everything you say will be done immediately.

I need help with this. Does "kılına zarar gelmez" mean "Would not harm a hair on somebody´s head"? And I suppose that "Bir dediğin iki edilmez" is an idiom... But what the heck does it mean? To pamper? I am confused. 

"Madem boynunu büktüm, ailenden ayrı düşürdüm seni"

Since I have made you lower your head and have seperated you from your family.

Where does the seni come from? I understand the first part, but the seni in the second part threw me off... ayrı düşürdüm is to think differently right? So, I have thought differently than your family... then the seni? Or maybe I am totally off...

Thank you for the one that will take his/her time to help! 

Thaaaank you, you are great as always! I really appreciate it.
