Ten years ago, I returned from my student exchange year in Texas. When I got out of the plane in Vienna, I had lost a lot of weight compared to the time I boarded my US-bound plane a year earlier (this is very unusual for exchange students – especially those in the USA). Immediately after my arrival, my family and I went on a two-week holiday in southern France. There, I drank up to nine liters of water or juice a day and went to the bathroom accordingly often. I ate loads of food but still lost weight. I was tired, quiet and glum. Reading books was hard because my eyesight was strangely distorted.
After our return home, we called my uncle, a doctor. He told us to go to the hospital immediately.
