Yes, as I recall, I think that eventually did dissipate. I am now 3 years on from onset. I see you are fairly new to t. Whether you have spontaneous remission, or habituation (which most of us do have), the result will much be the same. T and its effects will not exist for you anymore. This was the most difficult thing for me to grasp when I first started. The fight or flight experience had taken over.
My best advice to you is this: Try not to monitor t - the different sounds, the volume. Keep distracted. And at first, maybe mask if you can. What helped me is whenever I heard t, I would say to myself each and every time, even if I didn't believe it, I don't care, I'm too busy, I have more important things to worry about, I am so over it. I faked it til I made it. Once t has been triggered, it is very possible to train your brain back away from it again.
I know this may sound impossible to you right now. But I can tell you, from my experience, and many I have talked to outside this forum, that it is very possible. Look at the Back to Silence thread in the Success Stories on this forum for more info. Also, look at Julian Cowan Hill's youtube videos online.
Other healing factors are sleep, and calming your central nervous system. Walks, yoga, meditation, anything that works for you to calm those excitatory neurons. Magnesium may help also.
All this will not allow t to hang on anymore.
All will be well again. I am sure of it.
