I've have been listening to Julian Cowan Hill on U Tube for last couple of months and really recommend you to watch his helping strategies.
Your nervous system will strengthen, please get his book called Tinnitus from Tyrant to Friend it's available from Amazon.
No one feels at home with Tinnitus, you truely need to be your own best friend , because we all beat ourselves up about Tinnitus, with the whys and what's, but be as good as you can on eating healthy food, I've found eating pumpkin seeds, bananas, almonds, oily fish like tinned salmon or sardines, chicken, pork, cantaloupe, pineapples , green tea, all help, no alcohol, no caffeine.
Download if you can and play yourself as often as you like Joey Remenyls Body Scan, a simple step by step of calming the mind down and helping you cope with your T, but above all be gentle with yourself and your anxiety will lessen and improve, remember there there have been many who have started by taking baby steps, and completing self healing, including Julian Cowan Hill.👍
