Mo, I can relate to your situation very very well. Two years ago I had to retire from work because of a very very bad case of vertigo. Bad enough that they had to do a lambrinthectomy (spelling) on my left ear and grind out all of the inner ear. This was last June.
I have not been able to go up in a tree for over 5 years now, as it would set it off. I still can not go very deep into the woods because the dept perception plays havock with me. And if I am in the woods in the fall, and the wind is blowing and the leaves falling, some one will more than likely have to come get me.
I have gone to the extent of getting and making sure I have a phone with the gps tracking and make sure it is on when I go out. I leave all the info I can on where I am to a lot of people.
To this day, I can not walk in the woods before daylight under a flash light, or come out after dark. It just blows my total balance system.
I feel for you. It is not fun and for me, has taken a lot away that I always loved doing. I can not go and watch the water go down the river with out getting messed up. No canoe trips, no rides in the park. And altitude plays a big part in how my balance reacts.
So now, I just take my time, since my right side has to read all of my balance issues and try to keep me upright. It is not fun. I wish you the best.
