Today I cleaned the toilet and the whole bathtub/shower area, put wart remover on my foot, and did a lot of thinking about my phobia and contamination-related anxiety. So none of that was exactly fun, but my tub is very clean! 

It's weird. My emetophobia stems from one specific thing that happened when I was in college, and it sort of partially overlaps with fear of contamination/germs, but I can remember having a tendency toward that kind of anxiety for a long time. Since I was maybe twelve years old? It never caused a significant disruption in my life, but the tendency to waaay overreact to "dangerous chemicals" / warnings not to touch things was definitely there. And I don't think there's any initial experience that caused that? I don't know.
