I wish my audiologist had told me how bad tinnitus can get to make me realize how grateful I should've been back when it was more mild; mine was still maskable back then. I wouldn't hear it in an environment where the ambient noise was 40 dB. Still, tinnitus being new and all, caused catastrophic thinking, made me feel it was huge, and the worst thing imaginable. I had an obnoxious, low frequency hum that felt like vibrations in the ear, but it was still maskable and I couldn't hear it in most environments.
Now that my tinnitus worsened, I hear it everywhere and masking isn't effective. It now has an electrical, piercing quality where it's not just a noise anymore—it's a physical feeling, too. And it's painful, like electrical shocks zapping me frequently. It has literally reduced my life to ashes.
Had an audiologist told me early on, "You know, there's some people who can hear it everywhere, piercingly, with no ability to mask; in this very room, they'd hear it with no escape, no respite, a loud alarm...," then I think it would have helped; no joke, it might've put the whole thing in perspective for me. It might've made me realize I wasn't so bad off, as I would've compared it and sized it up to what they were saying. Early on, I think a lot of people—if not most—think their newly-formed tinnitus is catastrophic. It's important to suppress that thinking.
When the audiologist is lecturing a newbie on tinnitus, a little bit of scare tactics or a "fire and brimstone" approach might do some good. So that the person understands they need to be proactive and care for their ears. Most of the audiologists I've seen try to downplay the fear and assign anxiety as the cause of tinnitus.
Every time I say this or that caused it (a medication or listening to headphones, for example), the audiologist would say, "No, I don't think those are the causes. It's likely anxiety." And I knew for a fact what the causes were, based off what I had experienced first-hand. So it would be good for audiologists to warn about medications and supplements that can cause tinnitus, headphones, and being careful around loud noises, using protection when appropriate.
