I've got phantom pain from a missing limb.
For nine months my wedding binder was constantly by my side. Organized by tabs it had everything wedding planning related in it. I never went anywhere without it so if I needed a vendor phone number or wanted to double check something it was right at my finger tips.
I had come to depend on the binder and its presence. But now I no longer need it, and my bag is lighter. In a silly little way, I miss it.
