I've had Meniere's Disease since I was 17, and the tinnitus comes with it at no extra cost. Thirty five years on and all I can say is you just learn to cope. Some days it's louder and some days you don't register it despite it being a constant. It's tough at the start, but take some comfort in knowing you'll adapt. There are plenty of people out there who've gone through what you've experienced, so you've already got a support community.
