Martin that small period where you did not concentrate on the sound to me is a sign that you can eventually habituate. I wish there was a step-by-step guide to help but. It's thame thing but for extended periods. Goodluck martin.
Cullen, your words are very encouraging for all of us.
Of course sometimes I think why has this guy already habituated, but I am not.
But I remember stories where people took years to cope.
Today morning I was crying because of this BS in my head.
Then I pushed me starting the day. Was outdoors the whole day and had minutes where I did not concentrate on this sound. Also was very relaxed and my T was not a big issue. Maybe it was quieter, I don't know.
Now being home again having time and no distraction, T has my full concentration again.
A goog thing today was that I did not do any masking, not even a second. Masking is not really possible anyway.
I am sure that there will be a time in the future for everyone here where you no longer care, no longer react and simply live your life. T will become more and more a non-issue.
At least this is what I aim for.
Body and brain need much time adjust to this.
All the best for everyone.
