Is there a scientific way of cleansing the mind of impurity and OCD wiring?

I'm asking because of this:
I accidentally saw porn for the first time of my life and it was on 4chan in a completely unexpected place and it was full on black on white porn. I feel really fucking sick right now like my ears are ringing and my OCD is dialed up to 11. It's constantly flashing through my mind and forcefully associating with all my precious memories and my ears are ringing and I feel like I have a fever.

I feel like my brain chemistry is permanently fucked now I feel like a completely different person and the worst part is I got all this from a specific porn type that disgusts me. My life is a living hell now with the OCD/intrusive thoughts.
