At that point maybe just learn sign language? Sometimes I feel that speaking is overated. It's the best tool we have for connecting to other people, so you miss out on that, but even there it depends as much on the recipient. Nowadays we have many other tools and modes of communication so I think that by giving up the one thing that gives you most pain and suffering could actually do you more good. Kind of extreme suggestion but like you said, you have it extremely tough :/
