I got tinnitus during a particularly stressful (job related) situation in my life. It stayed for about a year or two. Now it is completely gone. I did not do any therapy. It seems what helped for me was "just" to get rid of the stress. I was in my early thirties at the time when I had it.
I have exactly the same experience. It began in my early thirties during a few stressful months. It stayed for about a year but then it was slowly getting better and was gone a few month later.
All cures seemed like snail oil to me, or like placebos for people who can't handle the thought that they can't do much about it. So I simply accepted it, knowing that it will either go away on it own or it won't. My partner was actually more stressed over it than me.
