I started hearing tinnitus a decade ago in a quiet room at night when I came back home after two years traveling the world at around 30 yo. Over the following months it became louder and noticed it more, then after maybe a year I could hear it all the time. During the day I could live with it but in the middle of the night I could not get back to sleep after waking up. It was causing a lot of anxiety because I was afraid of how much louder it may become.

I was thinking that maybe I cough something during my travels so I went to see a few specialists but they found nothing.

What I understand now is that the cause is probably all the vipassana meditation I did and some psychedelics I experimented with during my travel which opened some filters I had in my mind blocking sensor noise. It's the most plausible explanation for me.

The noise was probably always there, or maybe it got louder when I become older, but I never noticed it until it became disturbing.

A decade later the noise is still there, all the time, but it's not an issue at all anymore. It's not louder than before, and I have no negative feelings associated with it. I made peace with it and I can now easily ignore it, or to be more accurate, I can live with it and it'll disappear on its own after a short time until I put my attention back to it (voluntary or not).

As I'm writing this in a quiet room it's very loud, but that's fine, it just sensor noise. Soon enough I'll stop hearing it if I don't focus on it.

I hope reading this can help. I wish I had someone back then telling me that it would turn out okay to just accept it after doing some medical checks.
