Q.) How to I reduce the number of intrusive thoughts?

A.) One of the best way to reduce the number of intrusive thoughts is to focus on getting rid of your strongest kind of OCD. Focus on getting rid of the worst OCD that you struggle with and here's why. If you focus on your weakest one first, and tackle them from easiest to hardest, you are fighting an uphill battle. However, if you tackle the hardest one first and get a hold of that one, it's all down hill from there baby. This is by far the best approach. As far as decreasing the number of intrusive thoughts, Focusing on the hardest one will take up most of your mind.
