Hi, I read your query and can understand what you might be going through. Repeated occurrence of thoughts which are intrusive and cause distress are suggestive of obsessions. Obsessions can be in form of repeated thoughts that some harm will occur, regarding contamination, doubts, religion or sex. Most people do repeated acts or perform mental prayers to try to stop such thoughts. I would suggest you consult a psychiatrist for your symptoms. Treatment with medications like fluvoxamine, sertraline etc is effective. In addition, psycho-therapeutic treatment with exposure and response prevention is an effective option. Hope this information was helpful. Best wishes.
