I am unable to avoid some intrusive thoughts which pops up in my mind while studying or while doing any other things, then it takes me 10-15 minutes to convince myself in order to not take that thought seriously and I pledge to ignore such thoughts in future. But I feel the same amount of pain when such type of thoughts reappear in my mind and I feel extremely helpless in terms of ignoring those thoughts and it again take the same amount of time (and sometimes same argument too which I use to do with myself) to convince myself to ignore such thoughts. Now, for last 1 month, such thoughts started disturbing me so frequently that I am failing to concentrate in studies for more than 10-15 minutes and I use to get indulge in talking to myself in order to reduce the anxiety caused by thoughts which I don't like. It gives me headache after sometime. I can sense the problem to be growing day by day from last 1-2 months. Please suggest me immediate measures and way forward in this regard.
