Thanks for your question. I have searched on the internet for you and found the following options - there is a website called www.mind.org.uk which has information on the left hand side called 'helplines' - it explains that you can use textphone in order to speak with the people who can help you.
There is also the website www.textrelay.org that explains how to use an adaptation of an ordinary telephone, at no extra cost, in order to communicate with the person at the other end of the line. It says that thousands of people are unable to use the telephone without using this type of adaptation, so I imagine it must be very helpful once you have got used to it.
You mention that you have been to AA - if this is Alcoholics Anonymous (forgive me if it isn't) there is a website in America who runs the 12 steps programme on line by signing - they have limited times that you can access support on the phone, but their services are directed towards those who cannot hear. In order to take part in this, you require a computer, a web-cam, a high-speed internet and an email account. You can find them at www.dhh12.com/
I hope this is helpful and wish you well. Sarah
