Ah yes... this is typically normal though, as the human mind often desires control off itself. Without it, the mind can be lost. Its a conscious state of self reasoning I believe... one which we often must learn to let go off though with PTSD. Normal though... most people in the world struggle with it, and even when you do learn to let go and relinquish control to another with full trust, you still struggle keeping it that way.

You will often find soldiers, police, fire officers, etc, those who work in roles where you build team skills, you build team work to the point were if one fails, you could all die, so your brain learns to rely upon another and trust fully. Still can be challenging at times, and often the weakest link will be the one who cannot let go off that trust, or fails to perform their duty correctly. Sorry, just rambling in thoughts as it comes to me...
