Hang in there, you're at the bottom, so you're gonna go up to the surface eventually!!!There are so many wonderful people on this forum. I am so grateful for all the contact and for all those that reached out - thank you!. Its been good to try to support others as well. One person in particular who is habituating well sent me so many lovely mentoring pm's that he should be a saint. Despite all of this I'm at rock bottom. I've tried using drugs and not using them and a psychologist. I'm a total wreck from this intrusive noise, insomnia and massive anxiety after so many months. I don't know how people cope for years. I'm sure it has a lot to do with personality type, and other newbies please don't read this and let it worry you. I'm sure you will habituate just fine. But for me I just don't want to go on any more.
The most crappy aspect of what you describe is the anxiety, which is the one that causes insomnia, panic and makes the sound worse.
google neuroplasticity! (it works for anxiety like a charm)
