Phew Kokeshi, what a day. Hope you're getting some rest now. Sorry to hear about your Dad having to bounce straight back in.
Your appointments sound to me like good news, ie you're talking to people who have a bit more of a grasp of what this means to you, and I think that's a good thing, even if they're feeling a bit helpless.
Hearing aids: yes, they take a lot of getting used to, as you can see here.
I've had a fair few and each time it's been a shock putting a new one in. It can be quite hard (even if you're an experienced HA user) to know whether a new aid is wrongly set up or just new.
Anyway, stick with it and you might be pleasantly surprised. I have really terrible hearing (worse than yours) and I wear a hearing aid. It distorts everything such that I can't really recognise sounds, but I get a lot of useful info from it nevertheless.
A word of caution: I had the full CI workup in the UK and then sat on the waiting list for ages, despite being high priority, because the funding was completely inadequate. In the end I emigrated and 2 countries later, I'm finally in the countdown to surgery!
I don't mean to discourage you by saying that it might take a bit longer than everyone thinks - just be aware of this and don't pin all hopes on having the op right away. Then if it does happen it'll be a nice surprise.
I see you're going to have lipreading classes and I wanted to cheer when I read that, because I think that's the single biggest help you could have right now. It will make such a HUGE difference when you can lipread well.
CI, as you know, doesn't give you back normal hearing - it's intended to complement lipreading - so, think of it as preparation time for your implant.
Oh, and as Cristina mentioned, it's very useful to learn to fingerspell and teach family/friends. We do that and works well.
What else? oh, yes, someone mentioned a CI users' group - great idea. You can meet people with an implant and hear about their experiences. Where I used to live (in the south), the CI group had regular meetings with speakers on various topics, and there was a note taker typing what everyone said which was projected onto a big screen, so you could just read all the discussions off the screen. It was great.
Sorry, have written another novel, well done if you've got this far!
