I'm a hairdresser in a busy salon. It gets loud as everyone shouts above hairdryers. I'm sure this has added to my T.
Today my buzzing was causing me major anxiety but I can talk myself out of that and when I realized my blowdryer actually drowned out my buzz felt happy. I've found I have to out wit it, and that comes with practice. Mine is worse if I have sinus problems with it as it makes my ear louder more muffled hearing and swimmy head. All the best. The more you read here, the more you feel you can cope ... well, I have, hope you do too. You're far from alone
Also, anxiety heightens everything that I have learned, but it is hard to turn your head off and if you can learn to control that, you're on the right track. Easier said than done, but one hundred percent doable!
