Let me start by saying that I have autism and that a lot of my anxiety revolves around the concept of anything that's "spatial". Here are some examples:

- When I'm "physically trapped" and can go nowhere (elevators, cars, busses, lecture halls when there are lots of people sitting on either side of me)

- When I'm "socially trapped" in situations where it would be rude or weird to leave (when someone is giving a presentation for example)

- High ceilings, even the clouds

- Large structures/objects such as skyscrapers, planets

- Trying to fathom the size of the universe, or even earth itself. When I start thinking about it in the slightest I immediately get that startling adrenaline feeling

- The realization that I'm actually moving at extremely high speed because of the rotation of the earth etc.

Sometimes when I'm BOTH physically trapped (in a bus for example) and I look outside of the window, see the clouds extremely far above me and start thinking about the size of everything I exist in, my anxiety can get extremely high. Moments like that my vision starts to get kind of 2D and the whole universe kind of "feels" and seems unrealistic. I start to feel the panic coming up and can barely manage to stay calm.

I've read things about anxiety induced psychosis. Now when in the situation described above I'm starting to feel so afraid of my anxiety possibly increasing to the point of totally losing all sense of reality and into a full blown psychosis. And even more: what if I would hurt people around me if I'm ever in a psychotic episode? Or scream nonsense? Would I even be in control of my own body? I'm extremely scared of this concept.

I don't even know where I want to go with this post. Does anyone else have similar fears? Are my fears valid?
