I’m so sorry you’re suffering like this. I understand it’s hard and sometimes just getting out of bed is a challenge. If you’ve had intrusive thoughts for 27 years and haven’t acted on them yet take solace in that you probably won’t. (I say probably not because I think you will but because OCD is a quest for certainty which is fruitless) I think if your suffering this much it’s time to change therapists or do something new in your routine. Hang in there!
