I had the issue of having my hearing aids get repairs. I know it's not something everyone can do, but I always keep my old aids for this purpose. Though they aren't the most recent tech that my new ones are, it at least helped me get through that week of not having my new ones. But there does need to be something, maybe some sort of loaner aids to help with hearing when the aids getting fixed. I don't know if I could survive much without some sort of listening device, which is why I always keep my old pair so I at least have some hearing.
