I've had my tinnitus now for a few years. It started with a screeching and hissing sound in my head and I've acquired several other sounds in my ears over the time I've had it. I felt I'd habituated to the head noises quite well eventually, juSt with the passage of time. They didn't really bother me. Its the other noises I have trouble with. This past week or so the head sounds have come back in to my consciousness and I can't concentrate. They're almost impossible to mask and it's making me very depressed. I don't know why I'm so aware of them again after all this time. I don't want to fall into the trap of monitoring my tinnitus although it's difficult not to. Will it be possible to habituate again? Will it be a quicker process this time? Any advice appreciated.
