I have no idea whether this will be helpful to you because we’re also different even when the fears seem like there’s similar on the surface: my flying phobia definitely was made worse by OCD. I used to engage in this behavior where I’d compulsively listen to the sounds of the engine and over analyze it, and I really believed that if I put my headphones on and just enjoyed whatever audiobook I was listening to that the plane would be more likely to crash. It could crash that’s possible and me, listening to the sound of the engine is totally unrelated to whether or not the plane stays in the air. So see if you can figure out what your things are that are like that and see if you can stop engaging in them. My body still gets amped up every time I’m on a plane. I can’t seem to stop that from happening, but it’s not dangerous to be anxious. Just really uncomfortable.
