I‘m currently obsessed with noticing the voice in my head when I’m reading or writing something( like now) it bothers me because I have never noticed that and I guess i’ve never had that (?) Could that be something similiar to sensorimotor OCD? And does anyone has tips to stop „noticing“ it.

working with a NOCD therapist would be very good to get to the bottom of how to help yourself. Also. Thanks for sharing your current experience. I would say that you should be very proud of yourself for 1st noticing the anxiety, distress, and discomfort and letting those feelings of anxiety, fear, etc. be there.This is a perfect time to as I like to say "practice" ERP. Practice not analyzing any of those points you mentioned and place your attention on this present moment. Feel your feet on the ground, take a deep breathe, go for a walk, read, go hangout with a close companion, or play a sport. Not avoiding the discomfort, but choosing to do things you want to do and not give any attention to dwelling on that.The most important part being the response prevention. Not easy, but part of the work. When this type of situation occurs and we are in environments in which we are organically exposed to distress, use this as an opportunity to practice doing the work! This allows for two things; showing yourself you can handle and tolerate it, and also letting your body know that although you feel uncomfortable you are willing to keep doing whatever it is you are doing and getting on with your day! This is the foundation!
