I can so much relate to your anxiety and worry. I can also suggest looking on the American Tinnitus Association website.
Of course they ask for donations for research but there is good information on the site.
I'll attach the link below.
Main thing is to stay busy and active. Every day that you live with Tinnitus helps the brain habituate to it.
Keeping something to make "white noise" at night in your bedroom, like maybe a fan or some relaxing sounds like rain, waves on a seashore can help get to sleep.
Just remember you're not alone in this.
