ugh i feel you religious scrupulousity was hell for me when i was younger in large part because i would get other intrusive thoughts harm ocd etc punish myself for being a bad person then obsess over the fact that god could hear my thoughts and see how evil i was and compulsively pray for hours on end it was awful  what worked for me - no longer believing - unfortunately won’t work well for you but for what it’s worth i still get the first part of that scrupulosity cycle obsession over having done something morally wrong and compulsive reaction to address it and find that erp has been helpful hang in there though sorry you are dealing with this it sucks
