Go for it, it is important to you
When I was in middle school, I had a school guidance counselor who taught me to lipread. Several study halls each week we would meet and "talk"--she did not speak out loud, but I replied out loud. I was hearing impaired and did not have a hearing aid. It was a most wonderful gift she gave me. Life changing. I had the good luck to run into her many, many years later unexpectedly. When I could compose myself from the sudden overwhelming gratitude I felt, I approached her and tearfully thanked her for giving me such a meaningful and life-changing gift.
I am so fortunate that I had the chance to do that. It felt so good to say thank you.
