Tinnitus, particularly when you first get it seem to take over your life, the constant noise combined with a loss of hearing makes live very difficult and frustrating.
I am lucky I guess in I know what caused mine, an incident at my employment, and thus there was not much time taken up establishing the cause. I have no idea of your circumstances and also no idea if your recent change in weight has played a part.
Unless you have already done so may I suggest you go though appropriate medical investigation to see if there is a cause that can account for it, and if as a result it may be minimized.
I never found anything that helped except myself. Modern hearing aides do seem to have an anti-tinnitus setting, I never found they helped.
Concentrating on somethng you are interested in from a book to rideing can allow you to almost forget it for a while.
Now many years later I only seem to get the full effect if I concentrate on it, otherwise my mind has tended to block it out of my consciousness, still there but ignored. The only remaining problem is the accompanying hearing loss, and for that aids are improving. If I get a phone cal it goes straight to my aids in my ears and makes huge difference.
I hope it settles down for you
