I have a problem about a word that I've heard and now I can't get it out of my head and it is affecting me. I have OCD. How can I forget about it?

OCD. The short answer is, if you are on medication, to ask your doctor to adjust the dose or get you on new medication. Medications are prescribed differently for different people, and sometimes it takes some trials to find the right one. Also, you might try Cognitive Behavior Therapy and other behavioral therapies.
