did you take cognitive behavior therapy?does exposure and response was part of it?if no then you should go for these therapies.if yes then might be you have not completed you homework or you made exit from therapy.It could be possible that therapist was not experienced enough.so try again for cognitive behavior therapy with some other therapist.
It has been researched that combination of (therapy+medication )is best method to tackle ocd, so please consult a psychiatrist for medicine.
I went to therapy and it helped a little I wanted to try the medicine free route years ago but it's getting more and more prevalent
buddy ocd wont' go on its own , its a serious problem, the best solution is combination of medication and therapy. take both of them and your life would change. you can live a ocd free life
