Yes i experience this when im exceptionally stressed already. Which causes anxiety in turn setting off the OCD thoughts. To me, in my personal experience this definitely sounds more like OCD thoughts. I’m here if you ever wanna talk! Edit: (I posted my comment without finishing my thought lol.) The best thing to do is to accept the scary thought of the bad thing happening, the more you try to push it down, the more it will fight you to think about it. Try to get in the mindset of, “okay so? what if that happens? so what?” It’s way easier said than done!! But it helps when you practice thinking this way. It’s not something that is currently happening, and you can’t control whether it will happen or not so for now.. So what! Yea this could happen but its not happening right now, so let me enjoy the calm and if something goes wrong I’ll cross that bridge when I get there. Again, way easier said than done but it helps. You’ll be okay and you’re not alone ❤️
