Meditation has decreased my OCD by upto 70-80% in just 10 days. I suffer from Harm OCD. I have had depressive episodes of OCD where I couldn't even have the energy to walk. Been meditating since 10 days and the result have been more profound then I ever anticipated. My rumination has decreased by 90%. When I used to get intrusive thoughts, I would get totally consumed by them but now it feels like I am floating above them. The anxiety is still there but this time it feels more like I can observe it from above and eventually it dissipates. I have also been happier than I was even before I got diagnosed with OCD. But please, if you want to meditate don't start meditating with the intent of getting rid of OCD because with that thinking you won't. Meditation should be done for the meditation itself. Just like when you listen to music, the music itself is the point and not the end or the beginning. You need to have more meaning to it. For me, meditation was more about leading a spiritual life and on the path of experiencing enlightenment. If you are meditating to remain healthy, I am sorry, that's not how it works. Meditation is not a pill you take to get healthy and become happier, they are the by product of it. Like I said, don't meditate with the intent of getting anything out of it. This is why, spirituality gives more meaning to the meditation. I can suggest you some sources to get started if you're interested. But please do take care of the above. This may not 100% gurantee you will be able to decrease your OCD but I believe that it will and only if you understand the above and commit to doing it. Ah... It's a relief indeed! Meditation has transformed my mind. Don't mean to exaggerate but I know, I can feel how much of an impact it made. Being able to concentrate on task without having to ruminate on these thoughts has been the greatest feeling of relief. “To remain stable is to refrain from trying to separate yourself from a pain because you know that you cannot. Running away from fear is fear, fighting pain is pain, trying to be brave is being scared. If the mind is in pain, the mind is pain. The thinker has no other form than his thought. There is no escape.” - Alan Watts
