My last visit to the psych ward: main issue

One of the nurses there put a bunch of old bananas on the breakfast table. I asked her nicely to reemove them, bc that fruit triggers my anxiety (no idea why)
She putthem back in the kitchen, and the older nurse there could be heard asking why, followed by 4 seconds of silence, then "no, that's not possible. It's bullshit!"

I can handle people who initially laugh when I tell them ablut that phobia (for lack of a better word), but a mental health nurse refusing to believe it broke me.
