It's horrible isn't it.
I've got menieres though have managed to get it much more under control than it was by adapting myself and getting into a good medication routine (stemetil, betahistine and flixonase).
Have you had any tests done or further investigations? It took a long time for me to get anywhere with mine, my mum as well and GP's don't seem to understand it very well. Even after diagnosis I've had widely different advice from GP's.
It took me ages to get an initial referral and one GP just laughed at me until he saw me in a bad dizzy spell and realised there really was something wrong.
I went through ENT, neurology then a specialist neurologist specialising in ears who was fantastic.
I have adapted a lot naturally, hold onto things when in lifts or on escalators and walk close to walls without thinking now.
I've had to give a lot of stuff up, I used to do a lot of outdoor pursuits and especially things like riding and climbing just wouldn't be a good idea now.
I also avoid loud, crowded places, though partly as I have hearing issues as well. Heels are usually a no no unless I'm on a very good run.
I've got used to being clumsy, just one of those things now really and a running joke now at work with me missing and bumping into things and tripping over my own feet :)
Makes me a bit more antisocial but there are other things I do now like photography. The thought of having to adjust is often worse than the adjusting itself.
