You've probably experienced intrusive thoughts — bizarre, fleeting, sometimes inappropriate thoughts that cross your mind without warning. Although these can be weird to experience, they're totally normal. But for people with obsessive compulsive disorder these thoughts can become inescapable — leading to worry, compulsions and shame. Today we're talking about OCD, because it's often quite different from the stereotype of handwashing and lining up pencils. It can venture into taboo and dangerous thoughts, from paedophilia to violent harm.  So what does living with these unwanted thoughts feel like? And how much can treatment improve OCD symptoms? This episode covers some heavy topics from sexual abuse to suicide. There are also a few swear words. Please take care while listening.
