No need for apologies at all. I experienced similar tumultuous emotions after my very first reading of Gita. As others emphasized above, one has to study and analyse Gita (paarayana) in order to get most out of those verses. Not such an easy task with your proposed Upanishad paarayana, Iam afraid. Those are tough nuts to crack. Both the story line and the story telling style are unique and somewhat vexing, as presumably was the accepted norm/case in the academia those days. Good luck and welcome to hindu fold. Namaste.
