Lori,
Please take the time you need to heal. I was a teacher, too, and I know the pressure you feel not to miss school. Your recovery is primary. Physically and mentally you have already been through a lot. If you can, put yourself first right now.
You ask, "Do I technically have a disability now?"
My answer is "No, there is no such thing as a "technical disability".
I think you're a bit down right now because you have been blindsided with a situation that no one would have ever anticipated or predicted. When you start to feel better, you will have a better outlook. Try to focus on the positives in your life (I'm really not trying to sound preachy).
I hope your move to Tampa goes well. Moffit has an excellent reputation and if your follow-ups are there that should give you some peace of mind that you are working with the best possible team. I traveled 3 and 1/2 hours, one way, to Johns Hopkins for my follow-up appointments for two years, as well as seeing an ENT in Richmond.
And please don't worry about the insurance aspects (easy for me to say,no?), there are always work-arounds for things.
My best to you!
