[Anaraxes]

Sounds similar to a few Phobias to me (Crowds, Loud Noises, not so broad as Machinery / Technophobia), probably at -10 for the described problematic situations. Mechanically seems like a match: a self-control roll, with failure causing a Fright Check (perhaps that panic attack).

Why do you rule out "psychological conditions" -- especially since the description is a psychological condition? The phrase evidently means something that seems incorrect to you for the character. But any mental Disadvantage seems like it would be a psychological condition to me (not to mention a few Advantages).
