Translation of partícula

I fell asleep but woke up in the middle of the night. My stomach turned upside down and I could not hold myself anymore. I needed to vomit and ran to the bathroom. This occurred three times.
After getting up early I took a local car to get back to the center from where I took a coach to the long awaited city of San Cristobal de Las Casas. I have heard so much about this distant place.
Some of the people had invited me for dinner and I joined them. I soon found out that they were eating at their apartment and were cooking by themselves. I found myself peeling raw potatoes.
