Hello, FryOneFatManiac
(I was going to pm you, but my phone can't handle the pm link.)
The following encouragement may not be applicable to you, because I don't actually have a hearing problem. Throughout my childhood I thought I did, but my ears are fine- it's my brain that's the problem! I have auditory processing problems. Although I was terribly interested in languages as a child (especially German), I just assumed I was incapable of them. Very logically, I concluded that my frequent mishearing of people speaking my native language and my inability to pronounce various English consonants was going to be too big a barrier. At the least, I would need 1-1 tuition, I thought. I did Latin instead.
I realised that I had gradually got rid of almost every speech problem, and listening is only 25% of fluency. So, under occasional pressure from my husband ("you've always wanted to learn German, Jessie. Please give it a go, and stop telling yourself you can't do things", "but you can do rrr sounds mostly now! Ten years ago you thought you never would be able to", "so, you'll have to work harder and longer to reach the same level as other people- that's not the same thing as "impossible" ") I signed up. It's one of the best decisions I've ever made! It hasn't been easy, and I don't think I'll ever be an interpreter, but then I wouldn't apply to work in an English call-centre either! It turned out my problems aren't as insurmountable as I thought they were. And now, I do think it is possible for me to get to a similar level of ability to listen in German as in English. It might take a while, but learning how to say "Reading" instead of "wedding" took a while. It was still worth it. And learning German is a lot more enjoyable!
I have to work hard at home with CDs, DVDs, mp3s and what not, but my ability to understand spoken German is a lot better than it was when I was telling myself I couldn't do it!
It'll be September soon, the start of new courses. But in the mean-time, go to a library, and have a look at their language courses. You might really like Michel Thomas, for example. His tapes/CDs are set up to simulate actual small tutorial sessions.
If this is completely irrelevant to you, I apologise. I'm just a bit evangelistic now, because I don't like the idea of anyone else feeling the way I used to!
