I do feel for you, why can't we ever be confident and complacent, its a bummer. The anxiety is almost worse than the event. lets hope you get the attack and that does it for another 18 months.
After 7 years, i had an episode about 6 months ago, sudden huge rise in tinnitus and big drop in hearing and rather unbalanced. Kept waiting for the vertigo but it didn't happen, thankfully but spent weeks being wary of making any plans.
For the first time, my hearing hasn't bounced back at all in the Meniere's ear . I had a hearing appt this week and extensive testing. They said I was now severely deaf in that ear and any residual hearing was ineffective due to the tinnitus but an aid would help . Going to give that a go
Good luck
