I feel your pain buddy, I'm in a similar situation. Mine however, is more limited by my lack of confidence in creating a template, and lack of trusted and experienced stylists in my area. I'm sure when it gets to that point of shaving my head, I will be having the same "cold feet" as you. I guess I am relying on my only two options at this point. 1- hair piece or 2- shaving my head. If the piece is that bad I will resort to shaving my head. It is still a hard thing to swallow.

Good luck!
