Hi, welcome
I noticed my early symptoms when i began thinking that the horses i worked with were "quieter" when they stood on my right side -- DUH!!! It's funny now, but at the tiime, I was convinced that i was projecting some magic kind of "horse whisperer" mojo from my right side....whoooo boy..
You've found a great place to be: lots of supportive, knowledgeable people who can try to understand, help support and explain things to you. And if you havent already, the Acoustic neuroma associatioin has some great free materials you can request.
I hope that you are feeling good about having made your decision about treatment. The waiting for the procedure can be a little crazy-making, but I was able to work up until about 3 weeks prior to mine, so that helped. And communicating with folks on this forum was (and is) a true life saver.
I admire you so much for your concern for your students. Good, involved, cariing teachers are a national treasure. Your students are lucky to have you.
Wishing you all the best, and will be thinking about you and sending you good thoughts!!!
