I'm not sure where I read this (maybe even here on this site), it is part of a much larger article that I reread when I'm having a screechy day. It helps me:
'It is very reassuring to know that even though a person may always have tinnitus, they do not need to suffer from it, in fact they do not even need to hear it. Most people habituate over time by the effort of not reacting to it and this produces changes in the part of the brain concerned with suppressing or amplifying the signal. It may be obvious but obsessing over a sound is not the right way if you are trying to get your brain to ignore it. Anger and anxiety just draw attention to it and make it appear louder as your stress levels rise. Don't let this condition alter anything you do in life. Obviously take care with loud noise (as all people should) but try to live your life as if it is not there and this will aid natural habituation. Habituation of reaction is the primary goal and once that is even partially achieved, habituation of perception will automatically follow. Do not suppress the tinnitus sound as habituation cannot occur when the signal cannot be heard. It would be impossible to get over a phobia of spiders without facing the object of your fear and gradually feeling more at ease with it and this is the way to go with tinnitus. Don't focus on it but more importantly don't try to get away from it as you cannot habituate something that is not there! The best situation to be in is one where you hear the signal but remain calm and keep your reactions to a minimum. Even if this can only be done for 5 minutes this is a step in the right direction. Be kind to yourself and do whatever you can.'
