Is your hearing loss military-related? If so, you should be able to get a HA through your VA office/hospital. Are you at a certain disability percentage yet? (C&P?)
At any rate, I'm thrilled you are learning ASL. It will come in handy for you!
(My husband is a disabled vet, so if you have any military-related questions about getting help for your hearing loss, feel free to write or PM me)
