Suppressing your thoughts is the worst thing you can do for intrusive thoughts. They will only come back stronger and the feelings of anxiety will increase.

My experience with Pure O had included 5 hospitalizations, tons of therapy and some meds. I will say this: Medication was the least effective form of treatment for my intrusive thoughts. It was good therapy, with a fantastic psychologist, that really helped me to accept these thoughts. I am not saying you should stop taking your medication by any means, but it won't tackle the root of the problem.

If you are able, find a therapist who has experience dealing with intrusive thoughts. My former psychologist and I used to meditate together. When a "bad" thought came into my mind, I was terrified at first. But I was taught to watch these thoughts flow by, without judgement, and recognize them for what they are: mere thoughts. Eventually they no longer caused me suffering. It took a lot of hard work but it is so worth it.
