I have OCD. Does anyone else? Obsessive-compulsive disorder (OCD) is an anxiety disorder that makes people have unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), or behaviors that make them want to do something (compulsions). For example, I have to tap things or count to certain numbers in my head. I don't like stepping on cracks in the sidewalk, checking things a lot and my words and numbers have to always be touching the lines. Common symptoms include washing your hands a lot, cleaning, checking things, and repeating words. I'm just wondering because I don't meet many other people with OCD.
