To help you cope with tinnitus you should avoid stressful situations. Long periods of stress will make the tinnitus noises much louder than they would be if you are in relaxed state. So to help manage your tinnitus and not make it worse, you should try and live your life with the least amount of stress.
Use noises in the background to help drown out noise in your ears. A fan, the washing machine and the dishwasher can be just the kind of "white noise" that you need to take our mind off tinnitus. Focus on those noises in the background, or use them as a way to distract yourself, and you won't be as aware of the sound in your ears.
