Sorry to hear that! You have been really excited about that bike and I'd hate to see you have to give it up.
I'm 6' 1", so you are a lot taller than me, but I found Rok risers really helped. They are pricey, but they elevate your bars AND you can rotate them slightly up. It made a huge difference in my posture.
Also, try rotating your shifter up a notch. That may make your left foot a little more comfortable anyway.
