I wished I had knew about listening fatique growing up experiencing headaches, increased inability to focus, sleepy, zoned out, swinging mood, and so on. While it affect both deaf and hearing, it affect deaf people a lot more as they have to expend extra energy trying to hear and make sense of sound.
The good news is when I started learning sign language and stop trying to process spoken voices and conversation as much as I used to, many of these problems went away.
I must caution folks that it didn't happen overnight but gradually. Also people who are losing their hearing can experience a greater level of fatique trying to learn sign language as well. They can feel overwhelmed and feel like they are not good with language or that it's too hard and it isn't for them. I did feel that way when I first started learning sign language and it took me many years.
My suggestion is to hang in there and focus on the long run. Just be mindful of Listening Fatigue and don't add extra pressure on yourself to try to keep up or feeling bad about yourself. The best thing you can do is keep learning sign language and socializing with others who sign and I think you'll find many of these problems going away in the long run as they did for me.
