As the title says, I have a problem that I can't stand feeling unwell. When I start feeling a little sick or dizzy it soon leads to a meltdown that includes loud screaming and throwing on the floor. Otherwise I rarely have meltdowns. I had a cancer when I was 13 and these meltdowns started after that, so these are maybe not a classic autistic meltdown, but PTSD and panic attacks. Did anyone else have that cause of mwltdowns.
