Thank you for writing. I can’t make a diagnosis on the basis of a letter. For that you need to see a mental health counselor. But I can tell you that what you are reporting may be consistent with symptoms of OCD. On the other hand — and this is very important to consider — there is a difference between having some personal “quirks” and actual OCD. Many people have little rituals or habits or things they say to themselves when under stress that give them comfort or that help them manage some anxiety in doing a task. Many star athletes, for example, have rituals they engage in to give them luck. It is only when such habits start to interfere with social, occupational or academic functioning that they move from being quirky thoughts or behaviors to OCD. Further, to meet the criteria for OCD, the behaviors also have to be time-consuming (an hour or more a day) and cause you major distress. Your letter doesn’t indicate either.
If you do have OCD, you can get treatment for it. The most effective method seems to be a type of Cognitive Behavior Therapy called Exposure and Response Prevention (ERP) that is done in weekly visits with a trained therapist. Sometimes the therapy is augmented with some medication, usually an SSRI (selective serotonin reuptake inhibitor). For that reason, it is preferable to see a therapist who collaborates with a psychiatrist, as only a psychiatrist can prescribe medication. Reportedly, 70% of people treated this way learn to manage their symptoms or eliminate them.
I suggest you see a therapist for an evaluation. You may find that your habits are within the normal range. If you do have OCD, you can discuss what type of treatment might be most helpful for you.
I wish you well.
