Hi Martha,
My heart goes out to you. I suffer from your symptoms, but it seems your tinnitus is worse than mine. My AN was on the eighth cranial nerve, very deep inside near the brain stem. I had the middle fossa surgery to remove it.
My wife bought me a little electronic device that gives off sounds. You can choose all different types of sounds like the rain forest, the beach, birds tweeting etc. It has volume settings and a timer. I don't think it cost much, 35 bucks or something, but it may act as a distraction so you can sleep at night. Staying away from alcohol, caffeine, sulphides, nitrates, MSG, and processed meats like cold cuts can help, but I have found quality sleep to be the best help for tinnitus. It doesn't cure it, but it can soften it up a little. You have a long road ahead of you, so stay strong. You are among friends here, and post anytime, there are many wonderful and understanding people who are willing to just listen.
God Bless.
