I totally understand, I actually have my own theory which travel would fit into, I believe it is about
boundaries and how we deal with them. Really. It is then irritated by stress and our colon lining is a wall which we are somehow reacting to. I know I may sound like a nut but it makes sense to me. I am working on how I live my life as I believe all illnesses are manifestation which are trying to communicate something. All things change, nothing stays the same, I hope that via this change I can manage this condition by listening to it. Since this UC my life has changed and not neccessarily in a bad way, it has made me really focus on what is important and sort the wheat from the chaff. I found that pushing forward, impatience and wanting to live the old way was hindering my health. Who knows......
It is really hard to stay calm when travelling too, so my thoughts go out to you, this UC can really feel beyond control - excuse the pun! Take care
