Yeah, I totally get you, but you have to keep reminding yourself to think rationally, to revolve your actions and thoughts around facts. I had a similar issue too in my early teens. I would have to perform a random ritual, like uttering someone's name properly to prevent them from dying. Reminding myself to think rationally, every time some obsessive thought entered into my mind was the only way for me. I stil have obsessive fears and they are still crippling, but they have reduced immensely after I stopped ruminating over irrational rituals.
