While I'm no expert on your own specific illness, I sure do know about OCD--and noise! When I had my first (of three) clinical depresions--aka "breakdowns!"
--one of the many horrible anxieties that plagued me for the first time ever was noise. I still remember waking up the first morning after this depressive breakdown....and being horrified that just the sound of my clock ticking, next to my bed, was unbearable. This, of course, was part of my entire brain chemistry coming "unwired"--any sort of stimulation at all was unbearable. Along with many other symptoms, I could not be in a room with more than one person, could not stand a radio or television on....anything that produced what sounded to me like overwhelming noise. The anxiety was overwhelming.
At the time of this depression, I had been experiencing bad OCD (though at the time---many moons ago--I did not have the faintest idea of what OCD was!!) All I knew what that I had to rethink every single conversation with someone who was important to me to the point where all the possible permutations started to look like a tree diagram in my brain--one main trunk--with a hundred possible branches as to how that other person I spoke to might have reacted to what I said!! It was murder. Sheer insanity. It took up much of my life. But I couldn't stop it.
What saved me were good old antidepressants. It took over three weeks, but gradually the reaction to sounds, unbearable hopelessness, and some of the OCD was lessened. Ten years ago, I began Prozac--a drug that for me cleared up 99 percent of my obsessiveness--something I did not believe was ever possible.
Anyway--I was just wondering if you had ever been prescribed antidepressants as well as the anti-anxiety drugs? Antidepressants do not work instantly--but when you and your doctor hit just the right drug at just the right level--they can, for some people, be lifesavers. You may not need them. But I wanted to at least point out that there may be a lot of depression within your OCD. I now take Wellbutrin and Prozac--with the occasion half a Klonipin if I'm in a very anxious situation.
I found a wonderful psychiatrist who specialized in drugs for both depression and OCD. It's just something to think about.....
Meanwhile, I do know how much you must be suffering. I long ago decided that not having peace of mind was far worse than any physical illness I'd ever gone through. I do hope you will find relief with a doctor who investigates your symptoms more closely.
best to you, Lynn
