Hi Angieber and welcome to the Forums!
First of all, let me say that I feel badly that you have had to experience everything you described. That is truly awful.
And let me say that one thing I have learned from these forums is that nothing about acoustic neuromas is "normal." We all experience different challenges from each other. And then some people have no major issues at all before or after treatment.
Where did you have your gamma treatment? Was it at a major acoustic neuroma center? Many troubles (but far from all) come to those who received treatment from those who do not treat many ANs and are not skilled at treating them. I fear that might have happened to you, especially considering how your doctor told you to get used to it and referred you to a psychologist. That is not a very skilled statement.
Have you visited a vestibular therapist (not simply a physical therapist)? My vestibular therapist was very knowledgeable about acoustic neuromas and knew how to treat balance issues arriving from them. I went from being like I was drunk (and falling several times) to having better balance than most of the people my age (according to the tests the vestibular therapist gave me). I highly recommend that you see a good vestibular therapist if you can.
My taste issues eventually went away in time, but you have had them for five years! I would have thought they would have disappeared by now -- but, as I said, everyone's situation is different. Someone else might be able to give you better advice on your tinnitus. Mine is constant as well, but I am fortunate that I have learned to ignore it most of the time.
I wish you the best, Angiber, on your journey and hope that you receive some much needed resolution to these issues!
Don
