On days when I have that constant noise and my meds arn't really helping my doc has me take a xanax. I'm not necessarily advising it though. Sometimes the stress of the noise just spirals things down and gets me really worked up, and a xanax helps me not care abouit the noise. I also watch a lot of tv and listen to music or play computer games at the same time as a distraction. I've also found that I have more noisy days when I'm sleep deprived so it is really important for me to track my sleep schedule and make sure I'm getting enough, even if that means using sleeping meds like Ambien, which I feel also contribute to my tiredness during the day. I'm sorry you are having to experience this. Some days I get really wrapped up in the 'why me' stuff, and my therapist told me it's okay to have those days. Give yourself 24 hours, and permission to sit in that pitty pot and know that it's okay to feel that way. Then force yourself back to work. As a Christian I sometimes feel guilty for being mad at God for this when he has blessed me in so many other ways, and I don't know why He's allowed me to go through this stuff. I try to be positive and use it to help other's and tell myself that I wouldn't be able to talk to or relate to certain people without having experienced this yuck, but that doesn't make the yuck any less yucky, it does help a little with my feelings towards the situation some days though. I hope you find some peace and acceptance of the fact that you may never know why, all you can do is try to make the best of the hand you're dealt.
