No, those are different things. Intrusive thoughts are your brain telling you terrible things like you suck at your work or your hobbies, you’re worthless, your friends don’t actually like you, and hey remember that time you did a cringey thing in front of people? They’re not true, and you’re not intentionally having these thoughts, but your brain can’t easily rationalize them away. It’s usually something that builds up over a lifetime so that you don’t even realize it’s happening. Thats how so many people get stuck believing the intrusive thoughts.
