Some people will describe themselves as having pure O or pure C, but it all falls under OCD. There are numerous people who do have both obsessions and compulsions, but most will tell you that over time sometimes they'll loose the compulsions and the obsessions will pick up, or they'll loose their obsessions and the compulsions will pick up.
If your OCD is getting bad, I would suggest the following. You should make a trip to your physcian and have some routine blood work done to test your liver, kidney, and thyroid function, as any problems with these organs can sometimes exaggerate the symptoms of OCD. Once your doctor gives you the ok, as him/her to refer you to a cognitive behavioral therapist. A CBT is different than a regular therapist in the fact that they work with people specifically who have anxiety disorders, such as OCD. A CBT will help you "re-train" your brain to think in a different way to decrease your symptoms of OCD. You can also check the OC Foundations website, as they have listings of CBTs in all areas of the United States.
If you're not already seeing a thearpist, make an appointment with your primary care physcian to get the ball rolling and get into therapy. When choosing a therapist, make sure you ask a few questions before starting therapy like: 1. Do they use exposure therapy? 2. How long have they worked with people who have OCD and anxiety disorders? 3. Do they belong to the Association for Cognitve Therapists? 4. What is their stance on medication treatment for OCD? Let us know how you're doing.
