Didn't want to hijack other thread, but do want to wish you the best with tomorrow's switch-on! I used to work with Deaf people, but don't know much about implants. I do know how isolating and traumatic sudden, or even not sudden, deafness can be, an awful lot for you to deal with in a relatively short space of time, by the sound of it. But then I also know you are one brave and resourceful lady.
Wishing you the best possible success from your CI, and an end to isolation asap xxx
