Okay, so I didn't read all the responses, but I have your answer. You have Obsessive-compulsive Disorder. I didn't know other people had the exact same things annoying them, but I have it and that's what causes me to obsess over things like that. I'm surprised no one immediately responded with this answer since it's a common condition. I've had it since elementary school. I had lots of stress from bullies and bullying teachers, so I think that made it come out more. Mostly, people concentrate on the compulsions when they talk about OCD. I was diagnosed over a decade ago, while I was still in high school. They said I was textbook and that the things I'd done to try to treat myself were exactly what they would have done, but those addressed the compulsions (washing hands, etc.). The obsessions I have never seen treatment for other than drugs. I used to be on several things, with Risperdal making the largest difference. But it made me feel ravenous all the time, and when I had to come off of it so I could become pregnant, I suddenly found I had control of my appetite again. I had forgotten it was caused by the Risperdal. But the Risperdal DID make a HUGE difference. In fact, my husband knew I had OCD before we married and didn't know all those annoyances bothered me until about two years into the marriage when I got off the Risperdal. That's how effective it was. I could sit in church and not even notice that the person behind me was chewing their gum with their mouths open. I do remember the doctor saying it was an anti-psychotic (whatever that means), but that it can help with OCD.
So how am I doing today? Well, I'm thinking of changing my new psychiatrist (I moved a few times) to someone else 'cause this one doesn't give me anything that works for my extreme Anxiety Disorder (yes, that's an actual diagnosis), severe Major Depression, and, of course, my OCDs. I think he's more concerned with me losing the weight I've gained (I'm not quite 5'2" and I stopped weighing myself when I thought I was over 200 lbs, since I figured I would give up if I confirmed my suspicions. But I've lost a lot of weight...the twenty I gained being on one pill (can't think of the name right now, but I did nothing different and gained ten pounds in twenty days, LITERALLY)and I've started to lose the rest. I'm around 171-175 now, if you're curious, and that happened when I stopped that one drug...Lexipro maybe? And then later stopped the second treatment drug they ever tried on me, which I have been taking since diagnosis as a senior in high school (I'm 29 now). That one was called Celexa (generic: citalopram, one of those $4 prescriptions you hear about since it's gone generic now). It helped a lot, but I stopped taking it and had even more control of my eating. But now I'm depressed again. And I can't sit through church or even some movies. And I'm worried all the time. But I will find a new doctor and see what can be done to get me back in line. I have hesitated 'cause I ALSO want to lose the weight, but I also want my loved ones to not have to be afraid for me.
