So glad you found this forum for some very needed support. You have had unimaginable difficulties with recovery from your AN surgery.
Do a search on this site for those who have persevered and obtained permanent disabilty benefits. It sounds like that may be the route you are going to need to go.
Do not know if anyone ever mentioned a couple of things to you. Many of us have found that caffeine greatly increases the wobblies (or wonkyheadedness as we fondly call it here). Others have found other triggers that make it worse. Stress and fatigue are common triggers and it sounds like you are experiencing both of those. Even some meds can make it worse. If you have nausea issues from meds, you may have triggers for vertigo, as well.
A little about my situation that may help you. I have no working vestibular nerves on either side. Normally with the removal of an AN, your brain adjusts to the missing vestibular nerve and compensates by using the other "good" nerve on the non-AN side. Unknown to the doctor or me, I had only one working vestibular nerve at the time of my first AN surgery. When it was removed, I had MAJOR balance problems. Long story short, I spent months in outpatient and home-program vestibular rehab, learning how to compensate.
To this day, I have a great deal of trouble in all of the situations you described. Grocery stores (or any store with high aisles like that) are very stressful. Actually walking down any hallway creates unbalance but especially ones with busy carpets. Trying to stay upright in a crowd of weaving people is stressful. Soooooo, I have learned to grab a cart when in stores, stay near to the wall (and lightly touch it as I walk) in hallways, and stay to the outside perimeter when in a crowd.
Although I am a retired teacher, I think I could have returned to teaching, making the modifications necessary. However, not everyone can go back to work.
It sounds like you may have some other medical issues that are also involved in your recovery. I would certainly be very careful about driving when you are feeling dizzy.
Many thoughts and prayers that your doctor will have something to offer to relieve your terrible symptoms.

PS Just read your new post. Sometimes a poorly working vestibular nerve is worse than not working at all. The brain does not know how to compensate. Some AN patients have had to have the vestibular nerve totally removed to get relief. Ask your doctor if it was removed or see if tests can be done to determine if your vestibular nerve is misfiring or non-functional.
