Like you Lisa my T started in July ,had some better days and thought I am on the right road then bam a panic attack yesterday has left me fearful again .
I can sit with headphones on and just listen to the noise for quite some time but taking them off and listening to general noise I still notice the T almost everywhere but the reality is its not that loud .Hoovering and the T is apparent as is cutting the grass with ear defenders on but the actual noise in my right ear generally is much quieter.
As has been mentioned thinking of having this condition is almost as bad as the noise .Still Habituation hopefully will really kick in soon
