Those were the words that changed my direction also. Like you I was a get it outta here type, but then I saw 2 teams of docs; 1 wanted to get it out NOW, (wanted the surgery for his stats?) the other 3 said, "If in my head....I'd wait and see what it does..." Yes, a breath of fresh air for sure! I gave it 6 months, had zero growth, and the next one will be 9 months after that, on June 1.
The tinnitus is the hard part for me also. Mine is not high pitched, but a constant roar, motor like, and I believe it to be for the duration. But, do you notice it all the time, really? When you read or are really into thinking about something, do you fight it? 100% of the time? I finally have realized that I don't. I love quiet. I love to read and garden in my quiet times and wondered if I would ever hear "quiet" again, and I do! I get so involved that I do not hear the noise. Maybe it has happened over time, but there is hope, I think, for you also. Not that it will go away, but that you will not hear it all the time. I am not a doctor...just my thoughts!
Good luck to you! Put it out of your thoughts until July, enjoy life, then in July, think positive things. I read once "Worry is the mind's misuse of creativity." Good thought, eh?
