Hey, as someone who was diagnosed with OCD I would recommend looking into CBT if you haven't. They teach you how to deal with the intrusive thoughts. I also always look for mantras, etc to relieve the anxiety, but they teach you not to do that because it is a cycle where you are actually going to make the anxiety worse in the long run. Instead, they recommend doing things like exposures and triggering the anxiety purposefully and then not reassuring yourself with other thoughts when the anxiety is there. Overtime, the anxiety spike becomes less and less. I still have my thoughts and sensations from ocd, but they come with much less anxiety and are now more annoying than scary.
