I'm not sure if this counts, but dysenteri from drinking contaminated water.

2008 rendered me and my family homeless for 6 or so years. I was a teenager back then.

We were on vacation in Morocco. We were never a rich family, this vacation was something we planned several years in advance. But as we were in Morocco the whole economy collapsed and we were left stranded.

We made it into Spain by selling a bunch of our stuff. Then we were left stranded in Spain. Still realing from the shock of having lost everything, we were living in some plastic tents next to a river. We weren't allowed to drink the much cleaner water used by the local irrigation, so we took river water and boiled it.

Boiling it apparently wasn't enough. For a whole week I had snot-like slime with blood clots coming out of both ends. Nothing I ate stayed in or could be digested. Some locals who decided to help us said I looked like a skeleton, like someone from a concentration camp. I felt weaker and weaker, more tired, slept longer until I was basically asleep the entire day. I was told I was dying.

What saved me may have been activated charcoal. My mom had a whole pot of it and was feeding it to me with yogurt.
