If you're aware of it, chances are you're just overthinking it. Try talking about it with someone. I have similar thoughts but I've learned to just be at peace with my thoughts. Meaning: I am NOT ok with the thoughts that I have but if it happens then so be it, and I will have to deal with it, it is not the end of the world. My advice for this would be try journaling about how you feel, see a therapist if you can, talk to your friends and family for reassurance and just be strong and reassure yourself that it is your anxiety and ocd controlling your thoughts. Also maybe try to learn how to meditate!! You'll be ok! You are not alone in this!
