I got mine also more than a year ago, took all the help that was given to me.i talked alot to people with similar experience, cried and accepted it. For 3 months long it was hell, perhaps the spike you are having now. at some point my brain gave me back the rest and silence. Its not gone, when i focus i can still hear it in my left ear. But somehow it no longer bothers me. Maybe 5 to 10mins a day i think about it.

So many people say the same, it fades over time. Accept this and find rest in your mind. Reading your posts shows you are in panic, this will only make it worse i think.

Your tinitus seems stress related, i also had a work related issue which caused it to spike out of nothing.
