Your diet has a lot to do with your condition. If you get rid of the processed, fast foods, etc. you will feel much better. Supplements are also very important. Trace minerals and Omega 3's are imperative. It is very likely that you are deficient in trace minerals and this deficiency will alter the chemicals in the brain. You may even find after taking trace minerals for a while that you don't need your medication, making it possible to gradually reduce it altogether. Of course, this should be done under the supervision of a health practitioner.
Besides working on the emotional aspect of OCD, these physical aspects are extremely important.
