I've had severe Tinnitus for over a year due to a degenerative disease damaging my hearing and causing hearing loss. It's been hell, and it still is. It's unlikely to get better with time since the disease is known to make progress and worsen things.
No wonder suicide ideation is so high among T sufferers: http://journals.lww.com/thehearingjournal/Fulltext/2016/0700...
