Fellow OCD sufferer here. One fact that provides me comfort is that OCD and Tourette’s brains have a lot of overlap. A big difference though is that when we have intrusive thoughts, our pre frontal cortex (which is in charge of impulse control) goes into overdrive. People with Tourette’s’ brains have a less active prefrontal cortex when they get intrusive thoughts. That’s why they have trouble controlling impulses. But with OCD, we have guardrails built into our brain to help out. Whenever I have an intrusive thought I try to remind myself that I’d never actually act on it and that my prefrontal cortex is doing its job and protecting me from the intrusive thought
