@TheDanishGirl, I'm sorry that you are having such a difficult time.
I have spent some time on my hobbies today: knitting, painting/coloring and reading, but I still hear the T all the freaking time, and it is driving me insane
Spending time doing things you enjoy will help. And, unfortunately, some do hear it all the time, regardless of what they are doing. And, it will seem like it is driving you insane. The relentless ringing is maddening. As one who always hears the ringing regardless of what I do, the best advice I can give is too to focus your thoughts on something else (I know, much easier said than done). Sometimes I have to force myself to think about things, like doing difficult mathematics in your head (personally, I convert data to and from base64). You could try translating text to and from foreign language. You also mentioned that you enjoy painting (I am learning to draw), perhaps, if you are unable to paint, perhaps you could look at things for detail and think about how you would be able to recreate that detail in your painting. These may seem silly, or a waste of time, but they have worked for me, perhaps they may work for you as well.
@butterfly75 is correct, crying is good. You certainly do not want to suppress that for too long, obviously if you are somewhere where it is inappropriate you may want to wait until you are at a better location. For me, it is usually during my commute as I am alone in the car and have about 30 minutes on one, fairly straight, highway with minimal traffic to contend with. Also, reach out to friends and.or family (if possible).
I have counselling with an audiologist, but it does not help me, only leaves me frustrated, because she thinks T is all perception and all she says is listen to low level sounds/music, and try to relax, which does not make me feel better at all.
Can you get a new audiologist? While, technically, T is all perception (technically, everything we experience is "perception"), her attitude towards your tinnitus and your suffering is not helpful and it seems that she is neither acknowledging your suffering or alleviating it. In my opinion, your audiologist needs to not only deal with the sound(s) you are hearing but also help you with the emotional trauma you are experiencing as a result of your tinnitus. You need to find an audiologist that is willing to deal with the whole problem, and you as a whole person, meaning that she is willing to help you with not only the symptoms but the effects the symptoms are having on you.
@Bleep is correct, you will survive this.
Hang in there. I know you have had good days, you are just having some very bad ones right now, but the good days will return. It will get better.
