not exactly the same but i guess ill share anyway as its come to mind   in high school for about 4-5 months i started getting obsessive thoughts about pulling the fire alarms at school of course there were many fire alarms in the school and i had to walk past them each day no matter where in the building i was   every time i had to walk past one i knew where they all were i was so sure that i would pull the fire alarm and get in trouble for it being a false alarm and my brain would send me down the spiral of if the fire department comes to the school and its a false alarm they wont be able to actually help real emergencies and people will die and itll be all your fault  x200b  it was a painful time and i didnt tell anyone because i thought they would see me as a mischief-maker or crazy or both and that they wouldnt believe that i pulled the alarm due to ocd if i acted on it      it never actually happened because i was able to try to walk down the halls when others were around logic being that if others were around i wouldnt pull the alarm because i would get caught right away   x200b  honestly i dont really know how i survived that period of high school
