good job. Starting the meds can be make some people really anxious. I don't have any first hand experience with Citalopram, but keep in mind that 15 days is just the start for an SSRI. You're doc is probably just trying to slowly ramp you up to 20 to minimize potential SEs, though it would be nice to actually hear it from him. Even at this dose you're setting the stage for success. Do anything you can to relax and distract yourself. For me the best treatment for OCD is to be with friends, laughing.
Keep it up, andrea34, you're heading in the right direction!
