Probably but 40 db is only a mild loss and I didn't even wear hearing aids till I was about 11.
I do know what it is like to lose a sense at a later age though as I was sighted until I was 17 then I gradually lost all my sight (although some of it later returned so now I am just legally blind as aposed to totatally blind as I was at one stage). I was rather devistated about my sight loss. I won't claim that I wasnt. Even going so far as to attempt Suicide. However It wasn't blindness that bothered me so much as my perseption of blindness. Had I known capable deafblind people who were able to lead normal lives then I would not have gone to pieces in quite the same way.
I think Jillo is right when she says that she would cope better knowing how to communicate via ASL and knowing capable deaf people. I'm sure that Jillo would manage with the loss of her hearing. I manage with no hearing and only limited vision. I face discrimination but so did my mum because she was French and had mental health issues. Incidently I also seem to suffer mental health issues although fortunately for me it is on a periodical bases rather then a permament one. My life is like a game of snakes and ladders. I manage to climb. I've even managed to get volentary work dispite my deafblindness but then I have another episode. I find mental health issues a greater barier then Deafblindness.
