What I do ifs when I have negative thoughts I counter them with positive affirmations out loud . Some people have great success with mother mary 's rosary , chants there all kinds of tools . The thing is everything is energy pos energy will counter neg energy as proven by science . What I do is 3O mins in mornings and evenings everyday some times a hour . Also check out youtube there is a Danish doctor some videos in English others in Danish that uses a tapping method on the bridge of your nose ( guess it gets your mind of of the OCD )
