I wonder if she was vaxed. That is young, and so sudden. That said, being exposed to a toxic environment can exacerbate other conditions, and some people are more susceptible to different kinds of toxins and some less.
Many chemicals used regularly for personal care products, cleaning, pest killing and other uses are very toxic and Q also touched on this more than once.
I am pretty sure she innocently took 2 or 3 shots without knowing anything about them, like most people. We live in a liberal area and many took the poison.
