No, but being life-threatening certainly helps.
Yeah, do you really think that's how the majority of the world views tinnitus? Attempting suicide because of "something as insignificant as" tinnitus, you only come off as a psychiatric patient. Last week I went to the health-care centre, when I was suffering really badly and with bloodshot eyes. For the first time ever, I asked a day off (I've had tinnitus almost a decade and never missed a day), and the receptionist told me to f*ck off. Yes, as in f*ck off, there are people with real problems! Now aside from not smoking, I don't consume any alcohol - ever! - but if I did, I'm sure I'd get a lot more help! (I live in Scandinavia.)
